If work completes inline, then we should pick up a dependent link item in __io_queue_sqe() as well. If we don't do so, we're forced to go async with that item, which is suboptimal. This also fixes an issue with io_put_req_find_next(), which always looks up the next work item. That should only be done if we're dropping the last reference to the request, to prevent multiple lookups of the same work item. Outside of being a fix, this also enables a good cleanup series for 5.7, where we never have to pass 'nxt' around or into the work handlers.

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.
