commit 14edd87dc67311556f1254a8f29cf4dd6cb5b7d1 upstream.
Commit a02e4b7dae4551(Demark default hoplimit as zero) only changes the hoplimit checking condition and default value in ip6_dst_hoplimit, not zeros all hoplimit default value.
Keep the zeroing ip6_template_metrics[RTAX_HOPLIMIT - 1] to force it as const, cause as a37e6e344910(net: force dst_default_metrics to const section)
