Subject: [PATCH] can: kvaser_pciefd: Clear listen-only bit if not explicitly
 requested
References: bsc#1012628
Patch-mainline: 6.3.4
Git-commit: bf7ac55e991ca177f1ac16be51152f1ef291a4df

commit bf7ac55e991ca177f1ac16be51152f1ef291a4df upstream.

The listen-only bit was never cleared, causing the controller to
always use listen-only mode, if previously set.
