to underflow its module ref count to avoid being removed from the

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
