Fix the use of memory barriers
Introduce the smp_load_acquire() and smp_store_release() macros. Fix synchronization in io_uring_cq_advance() and __io_uring_get_cqe(). Remove a superfluous local variable, if-test and write barrier from __io_uring_submit(). Remove a superfluous barrier from test/io_uring_enter.c.
