sun4u: ensure kernel_top is always initialised

Valgrind reports that when loading a non-ELF kernel, kernel_top may be used
uninitialised when checking for an initrd.

Since there are no known non-ELF kernels for SPARC64 then we can simply
initialise kernel_top to 0 and then skip the initrd load process if it hasn't
been set by load_elf().
