bloblist: refactor xferlist and bloblist

Browse Source 
Refactor the xferlist to remove the relocating when bloblist passed
from the boot args.
Refactor bloblist init to use incoming standard passage by default
if a valid transfer list exists in the boot args.
For bloblist relocation, use the actual total size if it has a smaller
BLOBLIST_SIZE_RELOC.
