Johannes Berg f046dadb4d wifi: cfg80211: wext: fix IGTK key ID off-by-one
[ Upstream commit c8d7f21ead727485ebf965e2b4d42d4a4f0840f6 ]

The IGTK key ID must be 4 or 5, but the code checks against
key ID + 1, so must check against 5/6 rather than 4/5. Fix
that.

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.
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.
