David Sterba 1686570265 btrfs: handle directory and dentry mismatch in btrfs_may_delete()
The helper btrfs_may_delete() is a copy of generic fs/namei.c:may_delete()
to verify various conditions before deletion. There's a BUG_ON added
before linux.git started, we can turn it to a proper error handling
at least in our local helper. A mistmatch between directory and the
deleted dentry is clearly invalid.

This won't be probably ever hit due to the way how the parameters are
set from the caller btrfs_ioctl_snap_destroy(), using a VFS helper
lookup_one().
