bloblist: fix the overriding of fdt from bloblist
When a bloblist is valid and contains fdt, it explicitly means
a previous boot stage is passing transfer list compliant with
Firmware Handoff specification, thus the fdt from bloblist should
not be overridden with the ones from board or env variables.
