net: hns3: don't push link state to VF if unalive

Browse Source 
[ Upstream commit 283847e3ef6dbf79bf67083b5ce7b8033e8b6f34 ]

It's unnecessary to push link state to unalive VF, and the VF will
query link state from PF when it being start works.

Fixes: 18b6e31f8bf4 ("net: hns3: PF add support for pushing link status to VFs")
