iproute_lwtunnel: fix array boundary check
seg6_mode_types is made up of 5 elements, so ARRAY_SIZE(seg6_mode_types)
evaluates to 5. Thus, when mode = 5, this function returns
seg6_mode_types[5], resulting in an out-of-bound access.
Fix this bailing out when mode is equal to or greater than 5.
Fixes: cf87da417bb4 ("iproute: add support for seg6 l2encap mode")
