 Log Message:
 Apply patch from PR kern/34583 sent by Rhialto, quoting him:
 "Add a 3rd entry in the cache, which keeps the end position
  from just before extending a file.
  This has the desired effect of keeping the write speed constant."
 And yes, that helps a lot copying large files... always at full speed
 now. This closes my PR kern/30868 "Poor performance copying large files
 on msdosfs".
 Also remove a 2 if-statements testing the same condition, combine them.
 All that from Rhialto, thank you very much.
