Subject: net: hns3: stop sending keep alive msg to PF when VF is resetting
Patch-mainline: v5.1-rc1
Git-commit: c59a85c07e77a7669e5b4d2ffa878b6894ec3953
References: bsc#1126390
When VF is resetting, it can't communicate to PF with mailbox msg.
This patch adds reset state checking before sending keep alive msg
to PF.
