Moving dbus (or network-manager that is) to a later point in the
shutdown process won't really help.
It would have to be moved after S31umountnfs.sh, which in turn is run
after S20sendsigs.
So the dbus and network-manager daemon would be shut down too early
anyways by sendsigs (that's also the reason why S15wpa-ifupdown is run
before S20sendsigs. This also means that if you setup your connection
via wireless/WPA using the wpasupplicant roaming mode, you will
encounter the same problems as with network-manager).

I'm not saying, that quota is at fault here. I reassigned the bug mostly
because it's imho not a bug in network-manager. network-manager is
simply not conceived for such a use case.
network-manager is intended for highly dynamic network environments,
where networks come and go and where you switch between different networks.
Removing network-manager is probably the best "bug fix" there is atm.
For a static configuration with NFS mounts etc, as Johns' setup, I would
recommend to use plain ifupdown.

Cheers,
Michael

P.S.: What happens if you pull the network plug? Will quota then also
fail to stop? Is this a matter of how the nfs share was mounted (hard or
 soft)?
