[PATCH] unpack-trees: pass checkout state explicitly to check_updates()

Add a parameter for the struct checkout variable to check_updates() instead of using a static global variable. Passing it explicitly makes object ownership and usage more easily apparent. And we get rid of a static variable; those can be problematic in library-like code.
