core: do a commit after all addresses complete ACD/DAD

l3cfg has a "temp_not_available" list of objects that couldn't be
added to platform, but can be added once some preconditions become
true (for example, a IPv6 route with a "src" attribute requires a
non-tentative src address to be present).

Retry to commit those objects once all addresses have completed
ACD/DAD.

(cherry picked from commit 9a090fdf7b)
