[PATCH] fs/io_uring.c: remove unnecessary boolean instructions that add uops

[PATCH] fs/io_uring.c: remove unnecessary boolean instructions that add uops

[noah]

This patch drops unnecessary comparisons to turn return values into
booleans. There is no reason to do a != for cancelled and posted as
they can be set to a boolean directly more efficiently.
