btrfs-progs: -q/--quiet not accepted for "btrfs subvolume" subcommands

[Roman Mamedov <rm@romanrm.net>]

Hello,

# btrfs --version
btrfs-progs v6.6.3

# btrfs sub create --help
usage: btrfs subvolume create [options] [<dest>/]<name> [[<dest2>/]<name2> ...]

    Create subvolume(s)

    Create subvolume(s) at specified destination.  If <dest> is not given
    subvolume <name> will be created in the current directory. Options apply
    to all created subvolumes.

    -i <qgroupid>             add the newly created subvolume(s) to a qgroup. This option can be given multiple times.
    -p|--parents              create any missing parent directories for each argument (like mkdir -p) 
    
    Global options:
    -q|--quiet                print only errors 

# btrfs sub create -q test
btrfs subvolume create: invalid option 'q'
Try 'btrfs subvolume create --help' for more information

# btrfs sub create --quiet test
btrfs subvolume create: unrecognized option '--quiet'
Try 'btrfs subvolume create --help' for more information

Same for "snapshot". Maybe also some or all others, did not check further.

This is the case also on btrfs-progs versions 5.10 and 6.2.
