mlxsw: Fixes in GRE offloading

Petr says:

This patchset fixes a couple unrelated problems in offloading IP-in-IP tunnels
in mlxsw driver.

- The first patch fixes a potential reference-counting problem that might lead
  to a kernel crash.

- The second patch associates IPIP next hops with their loopback RIFs. Besides
  being the right thing to do, it also fixes a problem where offloaded IPv6
  routes that forward to IP-in-IP netdevices were not flagged as such.
