net: use core MTU range checking in virt drivers
hyperv_net:
- set min/max_mtu, per Haiyang, after rndis_filter_device_add
virtio_net:
- set min/max_mtu
- remove virtnet_change_mtu
vmxnet3:
- set min/max_mtu
xen-netback:
- min_mtu = 0, max_mtu = 65517
xen-netfront:
- min_mtu = 0, max_mtu = 65535
unisys/visor:
- clean up defines a little to not clash with network core or add
redundat definitions
