qns: increase active CIDs limit for interop

Currently the max active CIDs limit controls both the number of active
CIDs as well as the number of active paths, so while during rebinding
tests the CIDs don't change, we are still prevented from creating new
paths because of the limit, causing the interop rebinding tests to fail.
