io_uring: fail NOP if non-zero op flags is passed in

io_uring: fail NOP if non-zero op flags is passed in
commit 3d8f874bd620ce03f75a5512847586828ab86544 upstream.
The NOP op flags should have been checked from beginning like any other
opcode, otherwise NOP may not be extended with the op flags.
Given both liburing and Rust io-uring crate always zeros SQE op flags, just
ignore users which play raw NOP uring interface without zeroing SQE, because
NOP is just for test purpose. Then we can save one NOP2 opcode.
