Trond Myklebust 95a15bf999 NFSv4: Handle case where the lookup of a directory fails 
commit ac795161c9 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.
