The txq of vif is added to active_txqs list for ATF TXQ scheduling in the function ieee80211_queue_skb(), but it was not properly removed before freeing the txq object. It was causing use after free of the txq objects from the active_txqs list, result was kernel panic due to invalid memory access. Fix kernel invalid memory access by properly removing txq object from active_txqs list before free the object.

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.
