nvme/pci: move cqe check after device shutdown
Many users have reported nvme triggered irq_startup() warnings during shutdown. The driver uses the nvme queue's irq to synchronize scanning for completions, and enabling an interrupt affined to only offline CPUs triggers the alarming warning. Move the final CQE check to after disabling the device and all registered interrupts have been torn down so that we do not have any IRQ to synchronize.
