In 'seg6_output', stack variable 'struct flowi6 fl6' was missing
initialization.

with lwtunnels")

Suggeting this fix, spotted during code review while experimenting
with SRv6, although havn't encountered a specific issue during
experiments.
Was there any genuine intention to actually keep 'fl6' uninitialized?
