of: resolver: Fix device node refcount leakage in of_resolve_phandles()

Browse source

In of_resolve_phandles(), refcount of device node @local_fixups will be
increased if the for_each_child_of_node() exits early, but nowhere to
decrease the refcount, so cause refcount leakage for the node.

Fix by using __free() on @local_fixups.
