Bug 1403366 - Don't use nsDirectoryService::Create in nsDirectoryService::GetCurrentProcessDirectory. r=froydnj Back in the day, there was no global with an already initialized DirectoryService. But now there is, and, in fact, GetCurrentProcessDirectory already errors out if that global is not set by the time it's called. All calling nsDirectoryService::Create achieves is doing the check again and calling QueryInterface, which we don't need to do anyways.
