[SP08] re-calculate interface quota when limit reached

Some providers might hit the limit reached event prior to
others. Thus, re-calculate and update interface quota for
every provider is needed.

This change also removes the lock that held by NPMS while
requesting NSS force update, which seems unnecessary and
might cause potential deadlock in future.
