Patch 2/2: check existance of the correct (just created) registry key; also fix
a wrong comparison

This one fixes the glitches.

IntCreateRegistryPath creates a Device registry path from a given Driver
registry path; after building a possible path, it checks whether this already
exists (and returns an alternative one if it doesn't). This check was changed
by r51163 to check the provided Driver path, meaning the function will return a
non-existing path. That creates problems for the graphics driver and apparently
results in those glitches.

Additionally this fixes reversed comparison logic in checking for the numeric
NNN part in ControlSetNNN.

A third patch for better code readability might follow.
