can: dev: can_put_echo_skb(): propagate error in case of errors
The function can_put_echo_skb() can fail for several reasons. It may
fail due to OOM, but when it fails it's usually due to locking problems
in the driver.
In order to help developing and debugging of new drivers propagate error
value in case of errors.
