The md->wait waitqueue is used by both bio-based and request-based DM. Commitdbd3bbd291("dm rq: leverage blk_mq_queue_busy() to check for outstanding IO") lost sight of the requirement that dm_wait_for_completion() must work with all types of DM devices. Fix md_in_flight() to call the blk-mq or bio-based method accordingly.

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.
