Subject: [PATCH] staging: rtl8192u: ieee80211: Fix incorrect type in assignment

Added le16_to_cpu() conversion fixing the following warning in assignment detected by sparse: 

drivers/staging/rtl8192u/ieee80211/ieee80211_softmac.c:2157:30: warning: invalid assignment: +=
drivers/staging/rtl8192u/ieee80211/ieee80211_softmac.c:2157:30:    left side has type unsigned long
drivers/staging/rtl8192u/ieee80211/ieee80211_softmac.c:2157:30:    right side has type restricted __le16

 I wonder if this is the best approach, making payload_size u16 in ieee80211.h would fix this plus other three sparse warnings. Could we make payload_size u16 or it must be definitely le16?
