Trivial patch

A program that uses GetCurrentProcessorNumberEx frequently becomes very verbose
under Wine. The reason is the FIXME(..) stub warning of this method in
dlls/ntdll/rtl.c.

This method is actually fully implemented for most cases, and the verbose
message can be thus omitted, while keeping the warning for those cases where
there actually is something missing in Wine's implementation. 
Specifically, this method is fully implemented for systems with less than 64
logical processors. 

API docs quote: "Processor groups are numbered starting with 0. Systems with
fewer than 64 logical processors always have a single group, Group 0."

The attached patch implements the mentioned behavior.
