nwhitehorn 66620db565 Move NVME controller shutdown from being called as part of module unloading
to being called through the newbus DEVICE_SHUTDOWN() path. This ensures that
the NVME controller gets shut down before the device and bus disappear
and prevents data corruption on shutdown on at least Samsung EVO 960 SSDs.
