fpga: dfl: pci: fix return value of cci_pci_sriov_configure
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.
