Subject: net: hns3: remove unnecessary MAC enable in app loopback
Patch-mainline: v5.8-rc1
Git-commit: 01952206e17ee34b5fe32f211619ac59ec043990
References: jsc#SLE-14777

Packets will not pass through MAC during app loopback.
Therefore, it is meaningless to enable MAC while doing
app loopback. This patch removes this unnecessary action.
