Sascha Hauer b8e2885ebc wifi: rtw88: usb: silence log flooding error message 
[ Upstream commit 1f1784a59c ]

When receiving more rx packets than the kernel can handle the driver
drops the packets and issues an error message. This is bad for two
reasons. The logs are flooded with myriads of messages, but then time
consumed for printing messages in that critical code path brings down
the device. After some time of excessive rx load the driver responds
with:

rtw_8822cu 1-1:1.2: failed to get tx report from firmware
rtw_8822cu 1-1:1.2: firmware failed to report density after scan
rtw_8822cu 1-1:1.2: firmware failed to report density after scan

The device stops working until being replugged.

Fix this by lowering the priority to debug level and also by
ratelimiting it.

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.
