net/hns3: fix VF alive notification after config restore

Browse Source 
Currently in the VF reset scenario, the VF performs the set
alive operation before restoring the configuration completed,
which may cause the hardware to work in an abnormal state.

This patch fix this problem by set VF alive after restoring
the configuration is completed.
