staging: rtl8723au: Use struct ieee80211_mcs_info to describe MCS information

Browse Source 
The original RTL code defined the MCS information as a 16 byte array
and blindly applied it's masking over the full array, ignoring the
fact that only the first 10 bytes describe the rx_mask and the rest
are different fields.
