Simplify exec_permission_lite() further

This function is only called for path components that are already known
to be directories (they have a '->lookup' method).  So don't bother
doing that whole S_ISDIR() testing, the whole point of the 'lite()'
version is that we know that we are looking at a directory component,
and that we're only checking name lookup permission.
