Correct the check if a plex is accessible in case it is not up.
...
This makes degraded RAID5 plexes actually work.

Correctly calculate what to do and how to retry a request to a plex when
...
the previous one failed and there are more than one plex in the volume.
This could have led to a flood of error messages on the console and
probably a deadlock in certain situations.

worker thread may have been destroyed (e.g. during orphaning).
Make sure that objects get back their worker threads when they get a
new geom.

Re-vamp how I/O is handled in volumes and plexes.
...
Analogous to the drive level, give each volume and plex a worker thread
that picks up and processes incoming and completed BIOs.
This should fix the data corruption issues that have come up a few
weeks ago and improve performance, especially of RAID5 plexes.
The volume level needs a little work, though.
