net: remove MTU limits on a few ether_setup callers
These few drivers call ether_setup(), but have no ndo_change_mtu, and thus were overlooked for changes to MTU range checking behavior. They previously had no range checks, so for feature-parity, set their min_mtu to 0 and max_mtu to ETH_MAX_MTU (65535), instead of the 68 and 1500 inherited from the ether_setup() changes. Fine-tuning can come after we get back to full feature-parity here.
