kernel: vfs: don't notify output-only select events by default
Output-only events (B_EVENT_ERROR, B_EVENT_DISCONNECTED and B_EVENT_INVALID, with B_EVENT_INVALID masked out before passing down events) are used to indicate error, so they should not be notified if the vnode does not have select(). Bug: 13965
