For real PCIe drives, if we removed one drive, existing hotplug
monitor will trigger the remove callback twice, there is one
workaround for vfio-attached device hot remove detection which
will also trigger the hot removal callback. For now we add
the check in the bdev_nvme layer so that coredump will not happen.
Fix issue #606.
