io_uring/zcrx: rename dma lock

In preparation for reusing the lock for other purposes, rename it to
"pp_lock". As before, it can be taken deeper inside the networking stack
by page pool, and so the syscall io_uring must avoid holding it while
doing queue reconfiguration or anything that can result in immediate pp
init/destruction.
