btrfs: ensure that file descriptor used with subvol ioctls is a dir
commit 325c50e3cebb9208009083e841550f98a863bfa0 upstream.

inode->i_op->lookup via lookup_one_len.
This patch ensures that the file descriptor refers to a directory.
Fixes: cb8e70901d (Btrfs: Fix subvolume creation locking rules)
Fixes: 76dda93c6a (Btrfs: add snapshot/subvolume destroy ioctl)
