slcan: Don't transmit uninitialized stack data in padding
struct can_frame contains some padding which is not explicitly zeroed in
slc_bump. This uninitialized data will then be transmitted if the stack
initialization hardening feature is not enabled (CONFIG_INIT_STACK_ALL).
This commit just zeroes the whole struct including the padding.
