Raymond Mao 0a31d3128e lib: fdtdec: validate bloblist FDT before consuming libfdt size 
Coverity Scan defects are observed in fdtdec_apply_bloblist_dtos(),
since the live FDT taken from the bloblist is passed to libfdt helpers
which consume header size/offset fields:
- fdt_open_into()
- fdt_pack()

Validate the bloblist FDT with fdt_check_full() before calling
fdt_open_into() and again after applying overlays before calling
fdt_pack(). This makes the libfdt consumers operate on a checked FDT
blob while keeping the existing flow unchanged.

Also normalize libfdt return codes from this path to errno values,
including the overlay callback path through bloblist_apply_blobs().

Fixes: b70cbbfbf9 ("fdtdec: apply DT overlays from bloblist")
