selinux: correct return values in selinux_socket_getpeersec_dgram()

Instead of returning -EINVAL if any type of error occurs, limit
-EINVAL to only those errors caused by passing a bad/invalid socket
or packet/skb.  In other cases where everything is correct but there
isn't a valid peer label we return -ENOPROTOOPT.

This helps make selinux_socket_getpeersec_dgram() more consistent
with selinux_socket_getpeersec_stream().
