Refactor the raid5_get_active_stripe() to read more linearly in the order it's typically executed. The init_stripe() call is called if a free stripe is found and the function is exited early which removes a lot of if (sh) checks and unindents the following code. Remove the while loop in favour of the 'goto retry' pattern, which reduces indentation further. And use a 'goto wait_for_stripe' instead of an additional indent seeing it is the unusual path and this makes the code easier to read. No functional changes intended. Will make subsequent changes in patches easier to understand.

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.
