btrfs: ensure that file descriptor used with subvol ioctls is a dir
commit 325c50e3cebb9208009083e841550f98a863bfa0 upstream.
If the subvol/snapshot create/destroy ioctls are passed a regular file

This patch ensures that the file descriptor refers to a directory.

Fixes: 76dda93c6a (Btrfs: add snapshot/subvolume destroy ioctl)
