When an unsolicited alert is received, we'll flag the card as halted so that
commands will not be retried. This is because often times the firmware will no
longer process any commands in this state and the driver will hold processes in
the dstate while waiting to retry the commands.
This is a debugging aide in that it simplies unloading the driver if the card /
driver is currently in a failed state.
