If we fail to submit a bio for whatever reason, we may not have setup a mirror_num for that bio. This means we shouldn't try to do the repair workflow, if we do we'll hit an BUG_ON(!failrec->this_mirror) in clean_io_failure. Instead simply skip the repair workflow if we have no mirror set, and add an assert to btrfs_check_repairable() to make it easier to catch what is happening in the future.

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.
