[PATCH] igb: fix misinterpreted return value of pci_enable_msix

[Stefan Assmann <sassmann@redhat.com>]

From: Stefan Assmann <sassmann@redhat.com>

In the igb driver a return value of 0 of function pci_enable_msix is
interpreted as an error case. The correct behaviour is to check < 0 for error
values.
