Josef Bacik a941c2d0c4 btrfs: do not allow non subvolume root targets for snapshot 
[ Upstream commit a8892fd71933126ebae3d60aec5918d4dceaae76 ]

Our btrfs subvolume snapshot <source> <destination> utility enforces
that <source> is the root of the subvolume, however this isn't enforced
in the kernel.  Update the kernel to also enforce this limitation to
avoid problems with other users of this ioctl that don't have the
appropriate checks in place.
