can: kvaser_usb: kvaser_usb_set_bittiming(): fix redundant initialization warning...

The variable err is initialized, but the initialized value is
Overwritten before it is read. Fix the warning by not initializing the
variable err at all.

Fixes: 39d3df6b0ea8 ("can: kvaser_usb: Compare requested bittiming parameters with actual parameters in do_set_{,data}_bittiming")
