spdk_pci_device_claim() can be used to ensure only one process at a time uses any given PCI device. Previously this was only used in the bdev_nvme driver - other apps like nvme/perf do not use spdk_pci_device_claim() and could effectively rip out the device from a running bdev-based app like the NVMe-oF target. So instead of modifying all of the nvme apps, put this logic into the core nvme driver instead so that all applications get the benefit transparently. Save the fd when the controller is constructed and then close it when the controller is destructed to handle the detach (including hotplug) cases.
