Subject: net: hns3: modify firmware version display format
Patch-mainline: v5.4-rc1
Git-commit: 923713730db9795ac0658cc207935c11b2bbd705
References: bsc#1154353

This patch modifies firmware version display format in
hclge(vf)_cmd_init() and hns3_get_drvinfo(). Also, adds
some optimizations for firmware version display format.
