Jim Harris e36f0d363e nvme/pcie, nvme/tcp: add cb_arg context tracepoint argument
This allows mapping an nvme_request back to the
nvme_bdev_io.

This requires bumping up the max number of arguments per
tracepoint.  5 was previously chosen as max since it
exactly fit in 64 bytes (1 cacheline) when all
arguments were stored as uint64_t, but now that we
support uint32_t arguments we can afford extra
arguments when some of them are uint32_t.  I've
bumped it to 8 so we can avoid having to touch
this value multiple times if we find some cases
where we need 7 or 8 args.
