mctp: Be explicit about struct sockaddr_mctp padding

Browse source 
We currently have some implicit padding in struct sockaddr_mctp. This
patch makes this padding explicit, and ensures we have consistent
layout on platforms with <32bit alignmnent.

Fixes: 60fc639816 ("mctp: Add sockaddr_mctp to uapi")
