uml: install panic notifier earlier
It turns out that if there's a panic early enough, UML will just sit there in the LED-blinking loop because the panic notifier hadn't been installed yet. This patch installs it earlier. It also fixes the problem which exposed the hang, namely that if you give UML a zero-sized initrd, it will ask alloc_bootmem for zero bytes, and that will cause the panic. While I was in initrd.c, I gave it a style makeover. Prompted by checkpatch, I moved a couple extern declarations of uml_exitcode to kern_util.h.
