mac80211: add driver ops wrappers
In order to later add tracing or verifications to the driver calls mac80211 makes, this patch adds static inline wrappers for all operations. All calls are now written as drv_<op>(local, ...); instead of local->ops-><op>(&local->hw, ...); Where necessary, the wrappers also do existence checking and return default values as appropriate.
