Subject: [PATCH AUTOSEL 5.7 040/388] staging: wfx: fix output of rx_stats on big endian hosts

From: Jérôme Pouiller <jerome.pouiller@...abs.com>

[ Upstream commit a823d6ecd4904e1a6ffb12964de88fb0bb4802f6 ]

The struct hif_rx_stats contains only little endian values. Thus, it is
necessary to fix byte ordering before to use them.
