Yes, it would be much better.

I think it can be done, the only driver that in some cases sets the tagset
pointer to NULL during reset is nvme-pci, but only after removing all
the namespaces.

So changing the timeout field in the tagset should be doable, the
only problem is avoid racing against nvme_alloc_ns().

I will try to come up with something.
