kqueue - Fix bad error path triggered by emacs
* Some device d_kqfilter functions were not setting ap->a_result,
leading to an error being improperly returned and knotes left
hanging. This led to a lockup and/or a panic when running emacs.
* Adjust dev_dkqfilter() to preset ap->a_result to 0 to fix the
problem and document it.
