OCSP stapling: added missing event handling after writing.

If we need to be notified about further events, ngx_handle_write_event()
needs to be called after a write event is processed.  Without this,
an event can be removed from the kernel and won't be reported again,
notably when using oneshot event methods, such as eventport on Solaris.
