When we queue a request via tw for execution it's not going to be
executed immediately, so when io_queue_async() hits IO_APOLL_READY
and queues a tw but doesn't try to recycle/consume the buffer some other
request may try to use the the buffer.
Fixes: c7fb19428d ("io_uring: add support for ring mapped supplied buffers")

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.
