io_uring: keep unlock_post inlined in hot path
This partially reverts
6c16fe3c16bdc ("io_uring: kill io_cqring_ev_posted() and __io_cq_unlock_post()")
The redundancy of __io_cq_unlock_post() was always to keep it inlined
into __io_submit_flush_completions(). Inline it back and rename with
hope of clarifying the intention behind it.
