abf6962144 api: simplify driver removal 
When we install the Wintun driver to the store, we get exact oem<nn>.inf
filename of the driver in the store we just installed. Since the
installation should be only temporarily, we should uninstall only the
driver we installed.

This also eliminates the need for iterating driver store speeding up
things.

The code we removed was inherited from the installer.dll, where it made
perfect sense to remove all installed Wintun drivers in the update
process.

254a900a76 api: bail out on _TRUNCATE truncation 
Silently ignoring truncation of the strings(like adapter and pool names,
registry paths etc.) leads to strange failures later down the road (like
registry key not found) masking the true reason of the failure. This
makes troubleshooting difficult.
