[PATCH] 2.5.69: mtrr: MTRR 2 not used, Bug #564

[Faik Uygur]

This one-liner fixes the mtrr not used bug, and addresses Bug #564
of Bugzilla.

mtrr_file_del was not decreasing the mtrr usage count so when
XFree86 was exiting, mtrr_close was trying to delete an already 
deleted memory type region with the freed mtrr.
