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.
