pxe_utils: Fix arguments to x86 zboot
bootm and zboot accept different arguments:
> bootm [addr [arg ...]]
> - boot application image stored in memory
> passing arguments 'arg ...'; when booting a Linux kernel,
> 'arg' can be the address of an initrd image
> zboot [addr] [size] [initrd addr] [initrd size] [setup] [cmdline]
> addr - The optional starting address of the bzimage.
> If not set it defaults to the environment
> variable "fileaddr".
> size - The optional size of the bzimage. Defaults to
> zero.
> initrd addr - The address of the initrd image to use, if any.
> initrd size - The size of the initrd image to use, if any.
In the zboot flow, the current code will reuse the bootm args and attempt
to pass the initrd arg (argv[2]) as the kernel size (should be argv[3]).
zboot also expects the initrd address and size to be separate arguments.
Let's untangle them and have separate argv/argc locals.
