io_uring: set -EINTR directly when a signal wakes up in io_cqring_wait We didn't use -ERESTARTSYS to tell the application layer to restart the system call, but instead return -EINTR. we can set -EINTR directly when wakeup by the signal, which can help us save an assignment operation and comparison operation.
