kernel - Flesh out nvme interrupts (non-msi for now)
* MSI/MSIX not working currently so just turn it off for the moment.
* Normal interrupt now operational. Implement a real nvme_intr() and
Cleanup some of our polling hacks now that interrupts work.
* Rearrange shutdown so admin polling continues to work while the devfs
disk infrastructure is being torn down.
* Tests with this little samsung mini-pcie nvme card:
120,000 IOPS (concurrent 512 byte dd)
1.5 GBytes/sec (sequential read uncompressable file through filesystem)
1.5 GBytes/sec reading via tar.
