Clang/scan-build complains about a possible buffer overflow in
ieee80211_wx_get_name:

.../staging/rtl8192u/ieee80211/ieee80211_softmac_wx.c:499:3:
warning: String copy function overflows destination buffer
	strcat(wrqu->name," link..");

.../staging/rtl8192u/ieee80211/ieee80211_softmac_wx.c:497:3:
warning: String copy function overflows destination buffer
	strcat(wrqu->name," linked");

The buffer wrqu->name is only IFNAMSIZ bytes big (currently 16),
so if we have a "802.11b/g/n linked" device we overrun the buffer by 3
bytes.

-> Use strlcopy / strlcat to populate the name.
This is done in a similar fashion in
staging/rtl8187se/ieee80211/ieee80211_softmac_wx.c

While at it cleaned some whitespace issues.
