Hmm, I think this patch will be orthogonal unless we put some of the opt-in
logic in the nvme_log_error() function itself.

Currently, we always log the error with the -1 sector value for passthrough
requests, which should be changed to print 0 so that we remain consistent
with the tracing infra. The same behavior should also be applicable when we
have the opt-in support, and the user decides to opt-in to log error for
passthrough requests.

That said, I am fine with this update going along with the opt-in support.
