[PATCH] xen/pcifront: avoid pci_frontend_enable_msix() falsely returning success
The original XenoLinux code has always had things this way, and for
compatibility reasons (in particular with a subsequent pciback
adjustment) upstream Linux should behave the same way (allowing for two
distinct error indications to be returned by the backend).
