btrfs-progs: qgroup create: accept only valid qgroupid

Browse Source 
Many qgroup commands accept the level/id format and also a path to
subvolume, the qgroup id is derived from that. This does not make sense
for the create command as we can't create the 0/subvolid qgroup (thus
can't be derived from the path), only the higher levels.
