of: overlay: add_changeset_property() memory leak
[ Upstream commit 637392a8506a3a7dd24ab9094a14f7522adb73b4 ]
No changeset entries are created for #address-cells and #size-cells
properties, but the duplicated properties are never freed. This
results in a memory leak which is detected by kmemleak:
unreferenced object 0x85887180 (size 64):
backtrace:
kmem_cache_alloc_trace+0x1fb/0x1fc
__of_prop_dup+0x25/0x7c
