nfp: reorder SR-IOV config and nfp_app SR-IOV callbacks
We previously assumed that app callback can be guaranteed to be executed before SR-IOV is actually enabled. Given that we can't guarantee that SR-IOV will be disabled during probe or that we will be able to disable it on remove, we should reorder the callbacks. We should also call the app's sriov_enable if SR-IOV was enabled during probe. Application FW must be able to disable VFs internally and not depend on them being removed at PCIe level.
