OF: fix of_find_node_by_path() assumption that of_allnodes is root
of_find_node_by_path() is borked because of_allnodes is not guaranteed to
contain the root of the tree after using any of the dynamic update functions
because some other nodes ends up as of_allnodes.
Fixes: c22e650e66
of: Make of_find_node_by_path() handle /aliases
