When removing or resetting an mwifiex device, we don't remember to free
the saved beacon buffer. Use the (somewhat misleadingly-named)
mwifiex_free_priv() helper to handle this.
Noticed by kmemleak during tests:
echo 1 > /sys/bus/pci/devices/.../reset
unreferenced object 0xffffffc09d034a00 (size 256):
...

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
