Instead of only retrying the START STOP UNIT command if a unit attention
is reported, repeat it if any SCSI error is reported by the device or if
the command timed out.

Hi Avri,
Thanks for having taken a look. I chose "break" on purpose since the
only case for which I expect scsi_execute() to return a negative value
is request queue shutdown. If the request queue is being shutdown I
think we should break out of the loop.
Thanks,
Bart.
