net: hns3: Fix speed/duplex information loss problem when executing ethtool ethx cmd of VF 

Our VF has not implemented the ops for get_port_type. So when we executing
ethtool ethx cmd of VF, hns3_get_link_ksettings will return directly. And
we can not query anything.

To support get_link_ksettings for VF, this patch replaces get_port_type
with get_media_type. If the media type is HNAE3_MEDIA_TYPE_NONE,
hns3_get_link_ksettings will return link information of VF.

Fixes: 12f46bc1d4 ("net: hns3: Refine hns3_get_link_ksettings()")
