    qemu: Return real error message for block_set_io_throttle
    
    This patch will also adjust the qemuMonitorJSONSetBlockIoThrottle error
    procession so that rather than returning/displaying:
    
        "error: internal error: Unexpected error"
    
    Fetch the actual error message from qemu and display that
