The command is
btrfs subvolume set-default <subvolid> <path>.
It uses @subvolid to control the default subvolume and
@subvolid=0 has always been parsed into FS_TREE no matter
what subvolume @path points to.
So in order to set a subvolume to the default one, we need
to get the id of this subvolume first.
Also fix a typo:
s/sbuvolid/subvolid/g
