[NET]: Fix error reporting in sys_socketpair().
If either of the two sock_alloc_fd() calls fail, we forget to update 'err' and thus we'll erroneously return zero in these cases. Based upon a report and patch from Rich Paul, and commentary from Chuck Ebbert. Signed-off-by: David S. Miller <davem@davemloft.net>
