REQ_F_COMPLETE_INLINE is only needed to delay queueing into the
completion list to io_queue_sqe() as __io_req_complete() is inlined and
we don't want to bloat the kernel.
As now we complete in a more centralised fashion in io_issue_sqe() we
can get rid of the flag and queue to the list directly.

io_read/write and provide_buffers/remove_buffers are still using
io_req_complete() in their own function. By removing the
IO_URING_F_COMPLETE_DEFER branch they will end in complete_post path
100% which we shouldn't.
