Subject: scsi: ncr53c8xx: Use default @max_active for hostdata->work_q

hostdata->work_q only hosts a single work item, hostdata->main_task, and
thus doesn't need explicit concurrency limit. Let's use the default
@max_active. This doesn't cost anything and clearly expresses that
@max_active doesn't matter.

Hello,

Resending because I screwed up the cc list in the original posting. The
whole series can be viewed at:

  http://lkml.kernel.org/r/20230509015032.3768622-1-tj@kernel.org

It's not a must but it'd be great if I can route this through the workqueue
tree so that it can go together with other related and followup cleanups.

Thanks.

This driver is normally referred to as ncr5380 or NCR5380. (It doesn't 
support any other member of the 538x family.)

No objection from me. I guess it's Martin's call?

As Finn pointed out, please make sure it's tagged NCR5380: instead of
ncr53c8xx:. Otherwise OK.

Will update and apply to wq/for-6.5-cleanup-ordered.
