can: bittiming: can_sjw_check(): report error via netlink and harmonize error value

If the user space has supplied an invalid SJW value (greater than the
maximum SJW value), report -EINVAL instead of -ERANGE, this better
matches the actual meaning of the error value.

Additionally report an error message via netlink to the user space.
