[PATCH v3 02/13] io_uring/cmd: kill one issue_flags to tw conversion

[Pavel Begunkov <asml.silence@gmail.com>]

io_uring cmd converts struct io_tw_state to issue_flags and later back
to io_tw_state, it's awfully ill-fated, not to mention that intermediate
issue_flags state is not correct.

Get rid of the last conversion, drag through tw everything that came
with IO_URING_F_UNLOCKED, and replace io_req_complete_defer() with a
direct call to io_req_complete_defer(), at least for the time being.
