Various cleanups to the main function for AIO kernel processes:

- Pull the vmspace logic out into helper functions and reduce duplication.
  Operations on the vmspace are all isolated to vm_map.c, but it now exports
  a new 'vmspace_switch_aio' for use by AIO kernel processes.
- When an AIO kernel process wants to exit, break out of the main loop and
  perform cleanup after the loop end.  This reduces a lot of indentation and
  allows cleanup to more closely mirror setup actions before the loop starts.
- Convert a DIAGNOSTIC to KASSERT().
- Replace mycp with more typical 'p'.
