Rotating Innodb Master key post upgrade crashes the server

Steps to repro:

1. create datadir on 5.7:

./bin/mysqld --no-defaults --datadir=`pwd`/data_57 --initialize-insecure --plugin-dir=/home/mohit.joshi/PS010819-percona-server-5.7.26-29-linux-x86_64-debug/lib/mysql/plugin/ --early-plugin-load=keyring_file.so --keyring_file_data=./data/mykey --innodb_sys_tablespace_encrypt=ON --innodb_undo_tablespaces=10

2. start the server on 5.7:

./bin/mysqld --defaults-file=~/my.cnf --datadir=`pwd`/data_57 --port=21000 --socket=/tmp/mysql_21000.sock --lc-messages-dir=./share --plugin-dir=/home/mohit.joshi/PS010819-percona-server-5.7.26-29-linux-x86_64-debug/lib/mysql/plugin/ --early-plugin-load=keyring_file.so --keyring_file_data=./data/mykey --max-connections=1024 --log-error --general-log --log-error-verbosity=3 --core-file --innodb_undo_log_encrypt=ON --innodb_temp_tablespace_encrypt=ON --innodb_redo_log_encrypt=MASTER_KEY --innodb_encrypt_tables=ON --innodb_sys_tablespace_encrypt=ON --innodb_undo_tablespaces=5 --innodb_parallel_dblwr_encrypt=ON --innodb_encrypt_online_alter_logs=ON --encrypt_tmp_files=ON &

3. Now run sysbench to run some Load:

mysql -A -uroot -S/tmp/mysql_21000.sock -e "create user sysbench@'%' identified with mysql_native_password by 'test';"
mysql -A -uroot -S/tmp/mysql_21000.sock -e "grant all on . to sysbench@'%';"
mysql -A -uroot -S/tmp/mysql_21000.sock -e "drop database if exists sbtest;create database sbtest;"

sysbench /usr/share/sysbench/oltp_insert.lua --mysql-db=sbtest --mysql-user=sysbench --mysql-password=test --db-driver=mysql --mysql-socket=/tmp/mysql_21000.sock --threads=1000 --tables=100 --table-size=1000 prepare

sysbench /usr/share/sysbench/oltp_read_write.lua --mysql-db=sbtest --mysql-user=sysbench --mysql-password=test --db-driver=mysql --mysql-socket=/tmp/mysql_21000.sock --threads=100 --tables=100 --time=3000 --report-interval=1 --events=1870000000 --db-ps-mode=disable run &

4. Shutdown the server from client

5. Start the server on 8.0 using 5.7 datadir:

./bin/mysqld --defaults-file=~/my.cnf --datadir=/home/mohit.joshi/PS200819-percona-server-5.7.27-30-linux-x86_64-debug/data_57 --port=22000 --socket=/tmp/mysql_22000.sock --lc-messages-dir=./share --plugin-dir=/home/mohit.joshi/PS200819-percona-server-8.0.16-7-linux-x86_64-debug/lib/mysql/plugin/ --early-plugin-load=keyring_file.so --keyring_file_data=/home/mohit.joshi/PS200819-percona-server-5.7.27-30-linux-x86_64-debug/data_57/data/mykey --max-connections=1024 --log-error --general-log --log-error-verbosity=3 --core-file --innodb_undo_log_encrypt=ON --innodb_temp_tablespace_encrypt=ON --innodb_redo_log_encrypt=MASTER_KEY --default_table_encryption=ON --innodb_sys_tablespace_encrypt=ON --innodb_undo_tablespaces=2 --innodb_parallel_dblwr_encrypt=ON --innodb_encrypt_online_alter_logs=ON --encrypt_tmp_files=ON &

6. Execute on upgraded server:
ALTER INSTANCE ROTATE INNODB MASTER KEY;
