arch/x86/asembly_entry: reorder conditional stage entry macros
The path that just clears CAR_GLOBAL variables and jumps to the stage entry point needs another condition for separate verstage just after bootblock. However, the current conditional is a negative conditional so swap the logic around to make it easier to extend.
