The pvrdma code relies on the pvrdma_ring.h kernel header for some basic ring buffer handling. The content of that header isn't very exciting, but contains some (q)atomic_*() invocations that (a) cause manual massaging when doing a headers update, and (b) are an indication that we probably should not be importing that header at all. Let's reimplement the ring buffer handling directly in the pvrdma code instead. This arguably also improves readability of the code. Importing the header can now be dropped.
