bhyve: refactor NVMe IO command handling

This refactors the NVMe I/O command processing function to make adding
new commands easier. The main change is to move command specific
processing (i.e. Read/Write) to separate functions for each NVMe I/O
command and leave the common per-command processing in the existing
pci_nvme_handle_io_cmd() function.

While here, add checks for some common errors (invalid Namespace ID,
invalid opcode, LBA out of range).
