History
Scott Long ef3cf714a4 Provide locking for the ccb_bioq. This allows xpt_done() to be called without 
Giant held.  In camisr(), move the ccb_bioq elements to a temporary local list
and then process the elements off of that list.  This enables the list to be
processed by only taking the ccb_bioq_lock once and only for a very short
time.

ccb_bioq_lock is a leaf mutex, so it's fine to call xpt_done() with other
locks held.  This is just a very minor step in the work to lock CAM, but
it allows us to avoid some messy locking/unlock dances in certain drivers.
