monitor: Fix QMP ABI breakage around "id"

Commit 65207c5 accidentally dropped a line of code we need along with
a comment that became wrong then.  This made QMP reject "id":

    {"execute": "system_reset", "id": "1"}
    {"error": {"class": "GenericError", "desc": "QMP input object member 'id' is unexpected"}}

Put the lost line right back, so QMP again accepts and returns "id",
as promised by the ABI:

    {"execute": "system_reset", "id": "1"}
    {"return": {}, "id": "1"}
