net: chelsio: cxgb4vf: Fix an error code in cxgb4vf_pci_probe()
During the process of driver probing, probe function should return < 0 for failure, otherwise kernel will treat value == 0 as success. Therefore, we should set err to -EINVAL when adapter->registered_device_map is NULL. Otherwise kernel will assume that driver has been successfully probed and will cause unexpected errors.
