nvme: Be less verbose when cancelling I/O or admin commands

[imp]

Summary

When we're resetting, and there's outstanding I/O that we're cancelling,
only report we're cancelling the I/O once rather than once per
I/O. Likewise when we reschedule the I/O. We don't need to say for each
one that we're cancelling/rescheduling something, and then report the
I/O that we're doing. Likewise with cancelling admin commands (we never
retry them here, so a similar change isn't needed).

I'd just use !TAILQ_EMPTY() instead of TAILQ_FIRST() != NULL. Also while there I would remove extra STAILQ_EMPTY() before STAILQ_FIRST().

Great suggestion...

I would also maybe go ahead and spell out report.

OK. I'd already made the first change... And I spelled it out here and elsewhere.

Would it make sense to have the logging similar for Admin and I/O? I.e., either change this to done aborting outstanding i/o or change the Admin case above to done aborting?

Yes. I think it would.
Thanks!
