NFSv4: Handle case where the lookup of a directory fails
commit ac795161c93699d600db16c1a8cc23a65a1eceaf upstream.
If the application sets the O_DIRECTORY flag, and tries to open a
regular file, nfs_atomic_open() will punt to doing a regular lookup.
If the server then returns a regular file, we will happily return a
file descriptor with uninitialised open state.
The fix is to return the expected ENOTDIR error in these cases.
