Subject: [PATCH] can: kvaser_pciefd: Set CAN_STATE_STOPPED in
 kvaser_pciefd_stop()
References: bsc#1012628
Patch-mainline: 6.3.4
Git-commit: aed0e6ca7dbb8fbea9bc69c9ac663d5533c8c5d8

commit aed0e6ca7dbb8fbea9bc69c9ac663d5533c8c5d8 upstream.

Set can.state to CAN_STATE_STOPPED in kvaser_pciefd_stop().
Without this fix, wrong CAN state was repported after the interface was
brought down.
