Subject: [PATCH] scsi: aacraid: Fix sync fibs time out on controller reset
After controller shutdown, all sync fibs time out due to not knowing
about the switch to INT-x mode
Fixed by replacing aac_src_access_devreg() to aac_set_intx_mode() call.
Cc: stable@vger.kernel.org
Fixes: 495c021767bd78c998 (aacraid: MSI-x support)
