There is a potential race condition between skb_queue_len() and skb_queue_tail(), the former may get old value before updated by the latter. So use skb_queue_len_lockless() instead. And also use '>=', in case we queue a few SKBs simultaneously. Found while discussing a similar fix for ath10k: https://patchwork.kernel.org/project/linux-wireless/patch/1608515579-1066-1-git-send-email-miaoqing@codeaurora.org/ No functional changes, compile tested only.

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.
