Subject: selinux: support IPPROTO_SMC in socket_type_to_security_class()
IPPROTO_SMC feature has been added to net/smc. It is now possible to
create smc sockets in the following way:
/* create v4 smc sock */
v4 = socket(AF_INET, SOCK_STREAM, IPPROTO_SMC);
/* create v6 smc sock */
v6 = socket(AF_INET6, SOCK_STREAM, IPPROTO_SMC);
Therefore, we need to add code to support IPPROTO_SMC in
socket_type_to_security_class().
