hyperv: Implement netvsc_get_channels() ethool op
This adds support for reporting the actual and maximum combined channels count of the hv_netvsc driver via 'ethtool --show-channels'. This required adding 'max_chn' to 'struct netvsc_device', and assigning it 'rsscap.num_recv_que' in 'rndis_filter_device_add'. Now we can access the combined maximum channel count via 'struct netvsc_device' in the ethtool callback.
