Subject: [PATCH] lib: fix a crash in plist update
Problem:
Prefix-list with mulitiple rules, an update to
a rule/sequence with different prefix/prefixlen
reset prefix-list next-base pointer to avoid
having stale value.
In some case the old next-bast's reference leads
to an assert in tri (trie_install_fn ) add.
