[PATCH] interface-ip: stop setting prefix indicator flag when IPv6 prefix lifetime changes

[Alan Swanson]

Since hnetd has now been dead for years we can safely revert commit
a03216660797173fbe67866f75564e3fec9c1e8d which was causing unnecessarily
frequent interface triggers and service reloads for IPv6 prefix lifetime
changes.

Fixes: FS#713 https://github.com/openwrt/openwrt/issues/5723
Fixes: FS#1492 https://github.com/openwrt/openwrt/issues/6454
