enic: add ethtool get_channel support
Add .get_channel to enic_ethtool_ops to enable basic ethtool -l
support to get the current channel configuration.
Note that the driver does not support dynamically changing queue
configuration, so .set_channel is intentionally unused. Instead, users
should use Cisco's hardware management tools (UCSM/IMC) to modify
virtual interface card configuration out of band.
