ed5ccb3bee io_uring: remove priority tw list optimisation 
This optimisation has some built in assumptions that make it easy to
introduce bugs. It also does not have clear wins that make it worth keeping.

Fixed buffers are generic infrastructure, make io_import_fixed() opcode
agnostic.

46929b0868 io_uring: add io_commit_cqring_flush() 
Since __io_commit_cqring_flush users moved to different files, introduce
io_commit_cqring_flush() helper and encapsulate all flags testing details
inside.

27a9d66fec io_uring: kill extra io_uring_types.h includes 
io_uring/io_uring.h already includes io_uring_types.h, no need to
include it every time. Kill it in a bunch of places, it prepares us for
following patches.

df9830d883 io_uring: rw: delegate sync completions to core io_uring 
io_issue_sqe() from the io_uring core knows how to complete requests
based on the returned error code, we can delegate io_read()/io_write()
completion to it. Make kiocb_done() to return the right completion
code and propagate it.
