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_ecwmin_ecwmax;

   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.

Currently LEAP is defined to two locally but the identically named
global constant is 128 in <linux/ieee80211.h>.  In order for us to

storage which is currently not enough to hold the larger value.

This is now consistent with the similar struct used in

rtl8192u: don't trample on <linux/ieee80211.h> struct namespace

In order to start reducing the duplicated code/constants/macros in this
driver, we need to include <linux/ieee80211.h> to provide the defacto
versions.  However this driver has structs with the same name as the
ones in the main include, so namespace collision prevents us from doing
step #1.

Since the structs actually differ in their respective fields, we can't
simply delete the local ones without impacting the runtime; a conversion
to use the global ones can be considered at a later date if desired.

Rename the ones here with a vendor specific prefix so that we won't have
the namespace collision, and hence can continue on with the cleanup.

Automated conversion done with:

    for i in `find . -name '*.[ch]'` ; do \
      sed -i 's/struct ieee80211_hdr/struct rtl_80211_hdr/g' $i ; \
