ip6erspan: remove the incorrect mtu limit for ip6erspan
ip6erspan driver calls ether_setup(), after commit 61e84623ace3
("net: centralize net_device min/max MTU checking"), the range
of mtu is [min_mtu, max_mtu], which is [68, 1500] by default.
It causes the dev mtu of the erspan device to not be greater
than 1500, this limit value is not correct for ip6erspan tap
device.
Fixes: 61e84623ace3 ("net: centralize net_device min/max MTU checking")
