Events: fixed "port_dissociate() failed" alerts with eventport.

If an attempt is made to delete an event which was already reported,
port_dissociate() returns an error.  Fix is avoid doing anything if
ev->active is not set.

Possible alternative approach would be to avoid calling ngx_del_event()
at all if ev->active is not set.  This approach, however, will require
something else to re-add the other event of the connection, since both
read and write events are dissociated if an event is reported on a file
descriptor.  Currently ngx_eventport_del_event() re-associates write
event if called to delete read event, and vice versa.
