Since cfg80211 doesn't implement commit, we never really cared about that code there (and it's configured out w/o CONFIG_WIRELESS_EXT). After all, since it has no commit, it shouldn't return -EIWCOMMIT to indicate commit is needed. However, EIWCOMMIT is actually an alias for EINPROGRESS, which _can_ happen if e.g. we try to change the frequency but we're already in the process of connecting to some network, and drivers could return that value (or even cfg80211 itself might). This then causes us to crash because dev->wireless_handlers is NULL but we try to check dev->wireless_handlers->standard[0]. Fix this by also checking dev->wireless_handlers. Also simplify the code a little bit.

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.
