IB/mthca: Recover from catastrophic errors
Trigger device remove and then add when a catastrophic error is
detected in hardware. This, in turn, will cause a device reset, which
we hope will recover from the catastrophic condition.
Since this might interefere with debugging the root cause, add a
module option to suppress this behaviour.
