[PATCH v1 11/18] btrfs-progs: rescue chunk-recover: use global verbose option

[Anand Jain <anand.jain@oracle.com>]

Transpire global --verbose option down to the btrfs rescue chunk-recover
sub-command.

For example: Both global and local verbose options are now supported.
 btrfs -v|--verbose rescue chunk-recover
 btrfs rescue chunk-recover -v
