[V3,0/2] scsi/sd: make disk cmd retries configurable

Message

The following patches made over Martin's staging branch allow
the user to config sd cmd retries. I didn't allow the user to
set any old value and kept the max at 5. However, you can now
turn it off and rely on the transport error handler to decide
when to stop retrying. You can also decrease retries for cases
for disks where there is no use in retrying 5 times.

V3:
- really drop excess ()s

V2:
- Drop excess ()
- Add comment about forcing completion in the request sense
case
- Use kstrtoint

Applied to 5.10/scsi-staging, thanks!
