btrfs: fall back to global reservation when removing subvolumes
I recently did some ENOSPC testing that involved filling the disk
while create and removing snapshots in a loop. During the test cycle,
I ran into an ENOSPC when trying to remove a snapshot, leaving the fs
stuck in ENOSPC even after a umount/mount cycle.
This patch allow subvolume removal to fall back onto the global
block reservation in order to succeed when it would have failed
otherwise.
