Chen Gang 13996ca7af USB: uhci: check buffer length to avoid memory overflow 
for function uhci_sprint_schedule:
    the buffer len is MAX_OUTPUT: 64 * 1024, which may not be enough:
      may loop UHCI_NUMFRAMES times (UHCI_NUMFRAMES is 1024)
      each time of loop may get more than 64 bytes
    so need check the buffer length to avoid memory overflow

  this patch fix it like this:
    at first, make enough room for buffering the exceeding contents
    judge the contents which written whether bigger than buffer length
    if bigger (the exceeding contents will be in the exceeding buffer)
      break current work flow, and return.
