[PATCH v2 2/3] grub: Make grub_envblk_iterate() return an int

grub_envblk_iterate() is a void. Future functions will require the ability to interpret return codes from the iteration, so grub_envblk_iterate() should be an int. The value of 0 returned from the hook functions is overloaded and cannot be parsed by callers to grub_envblk_iterate() for error
