net: hns3: initialize the message content in hclge_get_link_mode()

[ Upstream commit 568a54bdf70b143f3e0befa298e22ad469ffc732 ]

The message sent to VF should be initialized, otherwise random
value of some contents may cause improper processing by the target.
So add a initialization to message in hclge_get_link_mode().
