[PATCH 02/12] io_uring: refactor io_submit_flush_completions()

[Pavel Begunkov <asml.silence@gmail.com>]

struct io_comp_state is always contained in struct io_ring_ctx, don't
pass them into io_submit_flush_completions() separately, it makes the
interface cleaner and simplifies it for the compiler.
