When the application using VF device exits abnormally, for example,
when it is killed by 'kill -9', kernel PF netdev driver also stores
the corresponding configuration table entries of VF device.

This patch fixes it by adding message of deleting VF configuration
table entry corresponds to the revision of kernel hns3 netdev
driver, the new message is added to notify the kernel PF netdev
driver to clean up the VF configuration initialization during VF
initialization.

This revision is compatible with the old version of kernel hns3
netdev driver. The old version of kernel pf netdev driver will
ignore this message.

Fixes: a5475d61fa34 ("net/hns3: support VF")
