Log Message:
Pull up following revision(s) (requested by xtraeme in ticket #206):
sys/fs/msdosfs/denode.h: revision 1.14

sys/fs/msdosfs/msdosfs_fat.c: revision 1.11
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.
