  Allocate a single CCB at the start of the main loop of the RAID monitoring
  kthread of the mpt(4) driver that hangs around for the entire lifetime of
  the thread.  Previously the driver would allocate a new CCB using M_WAITOK
  with a lock held each time it updated its state.  While here, use the
  CAM API for allocating a CCB rather than raw malloc(9).
