wifi: iwlwifi: mvm: fix recovery flow in CSA
If the firmware crashes in the de-activation / re-activation of the link during CSA, we will not have a valid phy_ctxt pointer in mvmvif. This is a legit case, but when mac80211 removes the station to cleanup our state during the re-configuration, we need to make sure we clear ap_sta otherwise we won't re-add the station after the firmware has been restarted. Later on, we'd activate the link, try to send a TLC command crash again on ASSERT 3508. Fix this by properly cleaning up our state.

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.
