PCI: iproc: Remove PAXC slot check to allow VF support

Jitendra Bhivare · Lorenzo Pieralisi · commit 4da6b4480766 · 2018-09-18T10:13:04.000+01:00
Fix previous incorrect logic that limits PAXC slot number to zero only. In order for SRIOV/VF to work, we need to allow the slot number to be greater than zero.
