net: hns3: refine the handling for VF heartbeat
Currently, the PF check the VF alive by the KEEP_ALVE
mailbox from VF. VF keep sending the mailbox per 2
seconds. Once PF lost the mailbox for more than 8
seconds, it will regards the VF is abnormal, and stop
notifying the state change to VF, include link state,
vf mac, reset, even though it receives the KEEP_ALIVE
mailbox again. It's inreasonable.
This patch fixes it. PF will record the state change which
need to notify VF when lost the VF's KEEP_ALIVE mailbox.
And notify VF when receive the mailbox again. Introduce a
new flag HCLGE_VPORT_STATE_INITED, used to distinguish the
case whether VF driver loaded or not. For VF will query
these states when initializing, so it's unnecessary to
notify it in this case.
