LP #1630825: Adding "chown" step to documentation "Restoring Individual Tables"

**Reported in Launchpad by Siddhant last update 22-11-2016 23:03:10

Referring to the process of "Restoring individual tables " with Percona XtraBackup which is explained under below mentioned link.

https://www.percona.com/doc/percona-xtrabackup/2.2/innobackupex/restoring_individual_tables_ibk.html

Need to add below step , for clarification and ease of the process

shell> chown -R mysql:mysql /datadir/db_name/table_name.*

Above step should be added after copying table_name.ibd and table_name.exp ( or table_name.cfg if importing to MySQL 5.6) files to databases home.
