Currently, FUSED operations are not supported by QEMU. As per the 1.4 SPEC,
controller should abort the command that requested a fused operation with
an INVALID FIELD error code if they are not supported.
Changes from v1:
Added FUSE flag check also to the admin cmd processing as the FUSED
operations are mentioned in the general SQE section in the SPEC.
