USB and (upcoming) SDIO support may sleep in the read/write handlers. Shrink the RCU critical section so it only cover the call to ieee80211_find_sta() and finding the ic_vht_cap/vht_cap based on the found station. This moves the chip's BFEE configuration outside the rcu_read_lock section and thus prevent "scheduling while atomic" or "Voluntary context switch within RCU read-side critical section!" warnings when accessing the registers using an SDIO card (which is where this issue has been spotted in the real world - but it also affects USB cards).

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.
