Norbert Slusarek 5e87ddbe39 can: bcm: fix infoleak in struct bcm_msg_head
On 64-bit systems, struct bcm_msg_head has an added padding of 4 bytes between
struct members count and ival1. Even though all struct members are initialized,
the 4-byte hole will contain data from the kernel stack. This patch zeroes out
struct bcm_msg_head before usage, preventing infoleaks to userspace.

Fixes: ffd980f976 ("[CAN]: Add broadcast manager (bcm) protocol")
