inet: Fix BUG triggered by __rt{,6}_get_peer().
If no peer actually gets attached (either because create is zero or the peer allocation fails) we'll trigger a BUG because we unconditionally do an rt{,6}_peer_ptr() afterwards. Fix this by guarding it with the proper check. Signed-off-by: David S. Miller <davem@davemloft.net>
