The ignore_ctl_error option should filter the error at kctl accesses, but there was an overlook: mixer_ctl_connector_get() returns an error from the request.
This patch covers the forgotten code path and apply filter_error() properly. The locking error is still returned since this is a fatal error that has to be reported even with ignore_ctl_error option.
