The current medium access timeout counter will be increased for
each command, so if there are enough failed commands we'll hit
the medium access timeout for even a single device failure and
the following kernel message is displayed:
sd H:C:T:L: [sdXY] Medium access timeout failure. Offlining disk!
Fix this by making the timeout per EH run, ie the counter will
only be increased once per device and EH run.
Fixes: 18a4d0a ("[SCSI] Handle disk devices which can not process medium access commands")
