From: Keller Jacob <jacob.e.keller at intel.com>

During initialization, the VF counts its rings by walking the TQDLOC registers. This works only if the TQMAP/RQMAP registers are set to map all of the out-of-bound rings back to the first one. This allows the VF to cleanly detect when it has run out of queues. Update the PF code so that it resets the empty TQMAP/RQMAP registers post-VFLR to prevent innocent VF drivers from triggering malicious driver events.
