Johannes Berg afc857bc2a iwlwifi: mvm: add notification size checks
We shouldn't trust the firmware with the sizes (or contents)
of notifications, accessing too much data could cause page
faults if the data doesn't fit into the allocated space. This
applies more on older NICs where multiple notifications can
be in a single RX buffer.

Add a general framework for checking a minimum size of any
notification in the RX handlers and use it for most. Some RX
handlers were already checking and I've moved the checks,
some more complex checks I left and made them _NO_SIZE for
the RX handlers.

README

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.
