NVMe: Use pci_stop_and_remove_bus_device_locked()

Race conditions are theoretically possible between the NVMe PCI device removal and the generic PCI bus rescan and device removal that can be triggered via sysfs.

To avoid those race conditions make the NVMe code use pci_stop_and_remove_bus_device_locked().
