qemu_monitor_json.c: remove unneeded cleanup label
qemu_monitor_json.c: remove unneeded cleanup label

qemuMonitorJSONBlockIoThrottleInfo uses a macro called
GET_THROTTLE_STATS that's defined outside of the function,
which references a 'cleanup' label. GET_THROTTLE_STATS is
only used inside qemuMonitorJSONBlockIoThrottleInfo (in fact,
the macro is undef right after it) thus it is safe to erase
the 'cleanup' reference inside the macro, then proceed
with the usual cleanup label removal inside
qemuMonitorJSONBlockIoThrottleInfo.
