Log:
SPARC64: fix NULL pointer reference when attempting kernel boot

When checking to determine whether to boot a standalone kernel, we would
inadvertently reference a NULL pointer if no path was found. Make sure
subsequent path processing is ignored when not booting a standalone kernel
so we fall through to normal Forth boot.
