[SERVICES]: Addendum to r73433 for ScmStartUserModeService:

Browse source 
- Use the correct capitalization for the desktop name (to be consistent with all the rest of our code);
- Fix DPRINT1 order of arguments;
- Reorganize a bit the code to avoid the memory leak if ImpersonateLoggedOnUser fails and the environment block was already allocated (caught by Ged Murphy).
