AHCI - Fix panic if additional I/O is queued during SATA error processing.
* If additional I/O is queued during SATA error processing the AHCI
driver was improperly trying to initiate the new I/O. This caused
the error processing code to assert on unexpected command activity.
* Fix by implying exclusive access mode when the error CCB is in use and
giving the error CCB queueing priority over all other CCBs.
