mctp: Allow keys matching any local address
Currently, we require an exact match on an incoming packet's dest
address, and the key's local_addr field.
In a future change, we may want to set up a key before packets are
routed, meaning we have no local address to match on.
This change allows key lookups to match on local_addr = MCTP_ADDR_ANY.
