Marc Kleine-Budde 8ab67da060 can: dev: can_put_echo_skb(): don't crash kernel if can_priv::echo_skb is accessed out of bounds 
[ Upstream commit 6411959c10 ]

If the "struct can_priv::echoo_skb" is accessed out of bounds, this
would cause a kernel crash. Instead, issue a meaningful warning
message and return with an error.

Fixes: a6e4bc5304 ("can: make the number of echo skb's configurable")
