hw/block/nvme: reject io commands if only admin command set selected
If the host sets CC.CSS to 111b, all commands submitted to I/O queues
should be completed with status Invalid Command Opcode.
Note that this is technically a v1.4 feature, but it does not hurt to
implement before we finally bump the reported version implemented.
