ath10k: zero arvif memory on add_interface() 

The private memory area in vif provided by
mac80211 isn't guaranteed to be zeroed.

This patch should fix issues when switching
between STA and AP interface types.

The tim_bitmap could become polluted by STA bssid
field (since it's a union), wep_keys array
could also become polluted with invalid pointers
and probably much more.
