nl80211: make rx filters config global (ANDROID)
The RX filters (wowlan) configuration is per interface
but this doesn't reflect the state in the kernel where it's
per hw device (effectively in Android global).
In JB this is more important as wpa_s uses up to 3 different
interfaces when running P2P+STA. Also, fix a minor bug
in nl80211_toggle_wowlan_trigger where the wpa_s wowlan state
changed even if configuring the kernel failed.
