Subject: [PATCH] staging: rtl8723au: Fix sparse warnings

Some struct fields in wifi.h are meant to be __le16 but were declared as
unsigned short.  This was reported by sparse:

  rtw_wlan_util.c:538:24: warning: cast to restricted __le16
  rtw_wlan_util.c:1544:29: warning: cast to restricted __le16
  rtw_wlan_util.c:1546:25: warning: cast to restricted __le16

This patch changes the types of the struct fields involved to be
little-endian which is what is received over the air and consistent with
relevant structs in include/linux/ieee80211.h.
