net: release reference to inet6_dev pointer
addrconf_prefix_rcv returned early without releasing the inet6_dev pointer when the PIO lifetime is less than accept_ra_min_lft. Fixes: 5027d54a9c30 ("net: change accept_ra_min_rtr_lft to affect all RA lifetimes") Cc: Maciej Żenczykowski <maze@google.com> Cc: Lorenzo Colitti <lorenzo@google.com> Cc: David Ahern <dsahern@kernel.org> Cc: Simon Horman <horms@kernel.org> Reviewed-by: Simon Horman <horms@kernel.org> Reviewed-by: Maciej Żenczykowski <maze@google.com> Signed-off-by: Patrick Rohr <prohr@google.com> Reviewed-by: Leon Romanovsky <leonro@nvidia.com> Signed-off-by: David S.
