bridge: remove unnecessary check for vtbegin in br_fill_vlan_tinfo_range
vtbegin should not be NULL in this function, Its already checked by the caller. this should silence the below smatch complaint: net/bridge/br_netlink_tunnel.c:144 br_fill_vlan_tinfo_range() error: we previously assumed 'vtbegin' could be null (see line 130) net/bridge/br_netlink_tunnel.c 129 130 if (vtbegin && vtend && (vtend->vid - vtbegin->vid) > 0) { ^^^^^^^ Check for NULL.
