nl80211: Fix RTM_DELLINK processing for bridge events

When a netdev is removed from a bridge, RTM_DELLINK message is received
with ifname (IFLA_IFNAME) pointing to the main netdev event though that
netdev is not deleted. This was causing issues with P2P GO interface
getting disabled when the netdev was removed from a bridge. Fix this by
filtering RTM_DELLINK events that are related to the bridge when
indicating interface status changes.
