net: use core MTU range checking in WAN drivers
- set min/max_mtu in all hdlc drivers, remove hdlc_change_mtu - sent max_mtu in lec driver, remove lec_change_mtu - set min/max_mtu in x25_asy driver CC: netdev@vger.kernel.org CC: Krzysztof Halasa <khc@pm.waw.pl> CC: Krzysztof Halasa <khalasa@piap.pl> CC: Jan "Yenya" Kasprzak <kas@fi.muni.cz> CC: Francois Romieu <romieu@fr.zoreil.com> CC: Kevin Curtis <kevin.curtis@farsite.co.uk> CC: Zhao Qiang <qiang.zhao@nxp.com> Signed-off-by: Jarod Wilson <jarod@redhat.com> Signed-off-by: David S.
