Previously the skb was allocated with headroom MCTP_HEADER_MAXLEN,
but that isn't sufficient if we are using devs that are not MCTP

This also adds a check that the smctp_halen provided to sendmsg for
extended addressing is the correct size for the netdev.
Fixes: 833ef3b91d ("mctp: Populate socket implementation")
