hw/nvme: fix compliance issue wrt. iosqes/iocqes

As of prior to this patch, the controller checks the value of CC.IOCQES
and CC.IOSQES prior to enabling the controller. As reported by Ben in
GitLab issue #1691, this is not spec compliant. The controller should
only check these values when queues are created.

This patch moves these checks to nvme_create_cq(). We do not need to
check it in nvme_create_sq() since that will error out if the completion
queue is not already created.

Also, since the controller exclusively supports SQEs of size 64 bytes
and CQEs of size 16 bytes, hard code that.
