mac80211: dont use interface indices in drivers
This patch gets rid of the if_id stuff where possible in favour of
a new per-virtual-interface structure "struct ieee80211_vif". This
structure is located at the end of the per-interface structure and
contains a variable length driver-use data area.
This has two advantages:
* removes the need to look up interfaces by if_id, this is better
for working with network namespaces and performance
* allows drivers to store and retrieve per-interface data without
having to allocate own lists/hash tables
