io_uring: clear IORING_SQ_NEED_WAKEUP after executing task works

In io_sq_thread(), if there are task works to handle, current codes
will skip schedule() and go on polling sq again, but forget to clear
IORING_SQ_NEED_WAKEUP flag, fix this issue. Also add two helpers to
set and clear IORING_SQ_NEED_WAKEUP flag,
