Perhaps these repeated three lines should be a routine like:
bool tcp_check_oom(struct sock *sk, int shift)
{
	bool tcp_orphans = tcp_too_many_orphans(sk, shift);
	bool tcp_oom = tcp_out_of_memory(sk);

	printks...

	return tcp_orphans || tcp_oom;
}

I like your previous suggestion better. It preserves the ability to write:
if (too_many_orphans) {
   do_something();
}
if (out_of_socket_memory) {
   do_something_else();
}

shrug. That isn't currently used and 
tcp_too_many_orphans and tcp_out_of_memory
could still be checked.

I think the routine could be moved out-of-line.
