ip_tunnel: Add fallback tunnels to the hash lists

Currently we can not update the tunnel parameters of the fallback tunnels because we don't find them in the hash lists. Fix this by adding them on initialization. Bug was introduced with commit c544193 ("GRE: Refactor GRE tunneling code.") Cc: Pravin Shelar <[email protected]> Signed-off-by: Steffen Klassert <[email protected]> Signed-off-by: David S.
