Subject: [PATCH] balloon: Fix a misleading error message

cherry picked from eeef44b3a583637265f602882a0d058a52e3a33b

The error message

    {"execute": "balloon", "arguments":{"value": -1}}
    {"error": {"class": "GenericError", "desc": "Parameter 'target' expects a size"}}

points to 'target' instead of 'value'.  Fix:

    {"error": {"class": "GenericError", "desc": "Parameter 'value' expects a size"}}

Root cause: qmp_balloon()'s parameter is named @target.  Rename it to
@value to match the QAPI schema.
