Patch to sys/dev/nvme/nvme_ns.c

Dell-branded Intel P4600 NVMe drives benefit from NVMe 1.3's NOIOB feature.
Unfortunately just like Intel DC P4500s, they don't advertise themselves as
benefiting from this...

The attached patch adds P4600s to the existing list of old drives which benefit
from striping.
