vxlan: leave multicast group when vxlan device down
vxlan_group_used only allows device to leave multicast group when the remote_ip of this vxlan device is difference from other vxlan devices' remote_ip. this will cause device not leave multicast group untile the vn_sock of this vxlan deivce being released. The check in vxlan_group_used is not quite precise. since even the remote_ip is same, but these vxlan devices may use different lower devices, and they may use different vn_socks. Only when some vxlan devices use the same vn_sock,same lower device and same remote_ip, the mc_list of the vn_sock should not be changed.
