hw/arm/boot: fix direct kernel boot with initrd 

Fix the condition used to check whether the initrd fits
into RAM; in some cases if an initrd was also passed on
the command line we would get an error stating that it
was too big to fit into RAM after the kernel. Despite the
error the loader continued anyway, though, so also add an
exit(1) when the initrd is actually too big.

Fixes: 852dc64d66 ("hw/arm/boot: Diagnose layouts that put initrd or
DTB off the end of RAM")
