io_uring: make io_alloc_ocqe() take a struct io_cqe pointer

Browse source 
The number of arguments to io_alloc_ocqe() is a bit unwieldy. Make it
take a struct io_cqe pointer rather than three separate CQE args. One
path already has that readily available, add an io_init_cqe() helper for
the remaining two.
