[PATCH] NFS: Fix lookup intent handling
We should never apply a lookup intent to anything other than the last
path component in an open(), create() or access() call.
Introduce the helper nfs_lookup_check_intent() which always returns
zero if LOOKUP_CONTINUE or LOOKUP_PARENT are set, and returns the
intent flags if we're on the last component of the lookup.
By doing so, we fix a bug in open(O_EXCL), where we may end up
optimizing away a real lookup of the parent directory.
