Simplify ResolveNTFunctionPtr (temporary)
Simplify ResolveNTFunctionPtr (temporary)

I want to test the theory that the issues we are observing here
are actually a race condition.
- The race condtion would be related with 2 operations that
are not thread safe:
1- check/creation of the map
2- search/insert on the map

I would like to air this CL on dev channel for a week and
observe the crash rate.
