[PATCH 1/3] cmd: pxe: reorder kernel treatment in label_boot

[Patrick Delaunay]

Reorder kernel treatment in label_boot at the beginning of the function.

This patch doesn't change the pxe command behavior, it is only a
preliminary step for next patch, build kernel_addr before parsing
the label initrd and fdt to build the next bootm arguments.
