Description of problem:
If quota is installed (so rpc.rquotad exists), the nfs init script
tries to stop rquotad even if RQUOTAD == no.  The result is a nasty
FAILED output during an nfs stop.

Version-Release number of selected component (if applicable):
nfs-utils-1.0.6-22

How reproducible:
Always

Steps to Reproduce:
1. /etc/init.d/nfs stop
2. set RQUOTAD=no in /etc/sysconfig/nfs
3. /etc/init.d/nfs start
4. /etc/init.d/nfs stop

Actual Results:
Shutting down NFS quotas:                                  [FAILED]

Expected Results:
The init script should not try to stop rquotad.

Additional info:

I'm not sure if this is a touchy subject or not.  Bug 91789 was filed
on RH9, and bug 121651 was filed on FC1 (both by others).  Both have
been set to CURRENTVERSION, but the fixes have not been fully applied.

I will attach a unified diff against the current FC2 script.
