rtl8192u: align local ieee80211_wmm_ac_param struct fields with global

The <linux/ieee80211.h> and this local file both have a struct of the
same name.  They also have the same field sizes and generally the
same fields, as can be seen here:

   ~/git/linux-head$ git grep -A4 'struct ieee80211_wmm_ac_param {'
   drivers/staging/rtl8192u/ieee80211/ieee80211.h:struct ieee80211_wmm_ac_param {
   drivers/staging/rtl8192u/ieee80211/ieee80211.h- u8 ac_aci_acm_aifsn;
   drivers/staging/rtl8192u/ieee80211/ieee80211.h- u8 ac_ecwmin_ecwmax;
   drivers/staging/rtl8192u/ieee80211/ieee80211.h- u16 ac_txop_limit;
   drivers/staging/rtl8192u/ieee80211/ieee80211.h-};
   --
   include/linux/ieee80211.h:struct ieee80211_wmm_ac_param {
   include/linux/ieee80211.h-      u8 aci_aifsn; /* AIFSN, ACM, ACI */
   include/linux/ieee80211.h-      u8 cw; /* ECWmin, ECWmax (CW = 2^ECW - 1) */
   include/linux/ieee80211.h-      __le16 txop_limit;
   include/linux/ieee80211.h-} __packed;
   ~/git/linux-head$

Here we just align the local field names with the main system one.  Then
we can add an include of the system one and delete the local copy in one
smooth step in a follow-on commit.

Not that the replacement:

 for i in `find . -name '*.[ch]'` ; do sed -i 's/ac_aci_acm_aifsn/aci_aifsn/g' $i ; done
 for i in `find . -name '*.[ch]'` ; do sed -i 's/ac_ecwmin_ecwmax/cw/g' $i ; done
 for i in `find . -name '*.[ch]'` ; do sed -i 's/ac_txop_limit/txop_limit/g' $i ; done

implicitly shows that only one of the three fields is currently used.
