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.
