nic_router: fix interface-local quota reporting

Browse Source 
The router used to ignore the value of the <report quota=".."/> attribute when
it came to determining whether an interface's report is empty or not.
Therefore, merely configuring <report quota="yes"/> didn't cause interfaces
(and their quota) to show up in the report. Instead, interface quota was
reported as side effect of <report stats="yes"/>. The commit fixes this
inconsistency with the README.
