Move fast check out of io_queue_next(), it makes req->flags checks in __io_submit_flush_completions() a bit clearer and grants us better comtrol, e.g. can remove now not justified unlikely() in __io_submit_flush_completions(). Also, we don't care about having this check in io_free_req() as the function is a slow path and io_req_find_next() handles it correctly.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
