* stage2/builtins.c (boot_func): Load the boot partition
	information, only if the address of the boot partition entry is
	set appropriately.
	(real_root_func): If ATTEMPT_MOUNT is false, call open_partition
	and if successful, call set_bootdev, to set the offset of the
	boot partition and the address of the boot paetition entry.
	IF ATTEMPT_MOUNT is false, don't set BOOTDEV. The BSD evil hack
	is useless with the command "rootnoverify" anyway.
	* stage2/disk_io.c (boot_part_addr): Initialized with zero
	explicitly, to emphasize that it is invalid.
