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.
