mac80211: disable BSSID filtering for mesh interfaces

Mesh interfaces are currently opened with the FIF_ALLMULTI rx filter flag set,
however there is no BSSID in mesh so BSSID filtering should be disabled by
setting the FIF_OTHER_BSS flag as well.  Also explicitly call
ieee80211_configure_filter for mesh.
