net: bridge: change return type of br_handle_ingress_vlan_tunnel
br_handle_ingress_vlan_tunnel() is only referenced in
br_handle_frame(). If br_handle_ingress_vlan_tunnel() is called and
return non-zero value, goto drop in br_handle_frame().
But, br_handle_ingress_vlan_tunnel() always return 0. So, the
routines that check the return value and goto drop has no meaning.
Therefore, change return type of br_handle_ingress_vlan_tunnel() to
void and remove if statement of br_handle_frame().
