[PATCH 2/2] of: fdt: fix unflattening of FDTs containing uncompressed paths

[Sascha Silbe]

Probably since commit dfbd4c6eff35 ("drivers/of: Split
unflatten_dt_node()"), unflattening an FDT containing uncompressed
node names (e.g. "/gpio@d4019000/gpio@0") will abort after scanning
the root node because fpsize wasn't updated to include the path len.
