Until now, rtl8xxxu_watchdog_callback() only fetches RSSI and updates the rate mask in station mode. This means, in AP mode only the default rate mask is used. In order to have the rate mask reflect the actual connection quality, extend rtl8xxxu_watchdog_callback() to iterate over every sta. Like in the rtw88 driver, add a function to collect all currently present stas and then iterate over a list of copies to ensure no RCU lock problems for register access via USB. Remove the existing RCU lock in rtl8xxxu_refresh_rate_mask(). Since the currently used ieee80211_ave_rssi() is only for 'vif', add driver-level tracking of RSSI per sta.

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.
