Richard Palethorpe 51fafff685 slcan: Don't transmit uninitialized stack data in padding ...

[ Upstream commit b9258a2cec ]

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.
