Subject: [PATCH 4.4 46/60] staging: wlan-ng: add missing byte order conversion

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Igor Pylypiv <igor.pylypiv@...il.com>

commit 2c474b8579e9b67ff72b2bcefce9f53c7f4469d4 upstream.

Conversion macros le16_to_cpu was removed and that caused new sparse warning

sparse output:
drivers/staging/wlan-ng/p80211netdev.c:241:44: warning: incorrect type in argument 2 (different base types)
drivers/staging/wlan-ng/p80211netdev.c:241:44:    expected unsigned short [unsigned] [usertype] fc
drivers/staging/wlan-ng/p80211netdev.c:241:44:    got restricted __le16 [usertype] fc

Fixes: 7ad82572348c ("staging:wlan-ng:Fix sparse warning")
