Subject: ice: write register with correct offset
Patch-mainline: v5.5-rc1
Git-commit: 395594563b29fbcd8d9a4f0a642484e5d3bb6db1
References: jsc#SLE-7926
The VF_MBX_ARQLEN register array is per-PF, not global, so we should not
use the absolute VF ID as an index. Instead, use the per-PF VF ID.
This fixes an issue with VFs on PFs other than 0 not seeing reset.
