  incore() is used to detect logical block number collisions, and other
  callers will check B_INVAL on return.  Do not return a false negative
  if the buffer we find happens to be B_INVAL as this could result in
  duplicate buffers in the buffer cache.  As of the red-black tree code,
  which detects duplicate entries, the case will immediately panic the machine.
