When an EEH occurs during device initialization, the port timeout
logic can cause excessive delays as MMIO reads will fail. Depending
on where they are experienced, these delays can lead to a prolonged
reset, causing an unnecessary triggering of other timeout logic in
the SCSI stack or user applications.

To expedite recovery, the port timeout logic is updated to decay the
timeout at a much faster rate when in the presence of a likely EEH
frozen event.
