[PATCH v2 10/16] btrfs-progs: rescue super-recover: use global verbose option

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

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

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

     HELPINFO_INSERT_GLOBALS, BTRFS_BCONF_UNSET, BTRFS_BCONF_QUIET
     bconf_be_verbose(), bconf_be_quiet()
    Drop verbose argument in btrfs_recover_superblocks()
