man/io_uring_enter.2: clarify io_uring_enter(2) SQPOLL return value

If we're using SQPOLL, then the return value doesn't really indicate
how many IOs were submitted, as the actual submission happens out
of line. It'll usually be what the application asked to submit, even
if that differs from pending entries in the SQ ring.
