commit 3c2760b78f90db874401d97e3c17829e2e36f400 upstream.
pci_driver.sriov_configure should return negative value on error and
number of enabled VFs on success. But now the driver returns 0 on
success. The sriov configure still works but will cause a warning
message:
XX VFs requested; only 0 enabled
This patch changes the return value accordingly.
