nvme-pci: remove nvmeq->tags
There is no real need to have a pointer to the tagset in
struct nvme_queue, as we only need it in a single place, and that place
can derive the used tagset from the device and qid trivially. This
fixes a problem with stale pointer exposure when tagsets are reset,
and also shrinks the nvme_queue structure. It also matches what most
other transports have done since day 1.
