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.
