[SCSI] mpt fusion: clear list of outstanding commands on host reset
A bug in the fusion driver was exposed by the switch to block timeout. Basically, drivers are supposed to terminate commands once error handling begins on them. The fusion apparently wasn't doing this. Under the old timeout regime, completions on terminated commands would by and large get ignored because of the way command timeouts used to work. The new block timers are very intolerant to this, though, becuase the request gets cleaned and freed.
