Subject: net: hns3: Refactor the mapping of tqp to vport
Patch-mainline: v4.15-rc1
Git-commit: 7df7dad633e2c6d43ee9b39c267ee0add9798384
References: bsc#1104353 FATE#326415

This patch refactor the mapping of tqp to vport, making the maping function
can be used both in the reset process and initialization process.
