mqueues: Partially sync with NetBSD.

This fixes the following critical issues:
* An invalid signal number passed to mq_notify() could crash the kernel
  upon the signal delivery.
* mq_send() to a full queue could crash the kernel due to NULL pointer
  dereference in timeout calculation.
* Likewise for mq_receive() from an empty queue.

Thanks to swildner@ for bringing this into my attention.
