[PATCH v2 6/6] target/riscv/riscv-qmp-cmds.c: check CPU accel in query-cpu-model-expansion |

Use the recently added riscv_cpu_accelerator_compatible() to filter
unavailable CPUs for a given accelerator. At this moment this is the
case for a QEMU built with KVM and TCG support querying a binary running
with TCG:
qemu-system-riscv64 -S -M virt,accel=tcg -display none
-qmp tcp:localhost:1234,server,wait=off
./qemu/scripts/qmp/qmp-shell localhost:1234
(QEMU) query-cpu-model-expansion type=full model={"name":"host"}
{"error": {"class": "GenericError", "desc": "'host' CPU not available with
tcg"}}
