[U-Boot] [PATCH] common: image-fdt: correct fdt_blob for IMAGE_FORMAT_LEGACY

[Peng Fan]

If condition of "(load == image_start || load == image_data)" is true,
should use "fdt_addr = load;", but not "fdt_blob = (char *)image_data;",
or fdt_blob will be overridden by "fdt_blob = map_sysmem(fdt_addr, 0);"
at the end of the switch case.
