Subject: net: hns3: not reset vport who not alive when PF reset
Patch-mainline: v5.2-rc1
Git-commit: cc645dfa89a747382beaf62d69daafe60fd1cd94
References: bsc#1104353 FATE#326415 bsc#1137201

If a vport is not alive, it is unnecessary to notify it to reset
before PF asserting a reset. So before inform vport to reset,
we need to check its alive state firstly.
