of: dynamic: Fix memleak when of_pci_add_properties() failed
When of_pci_add_properties() failed, of_changeset_destroy() is called to
free the changeset. And of_changeset_destroy() puts device tree node in
each entry but does not free property in the entry. This leads to memory
leak in the failure case.
In of_changeset_add_prop_helper(), add the property to the device tree node
deadprops list. Thus, the property will also be freed along with device
tree node.
Fixes: b544fc2b8606 ("of: dynamic: Add interfaces for creating device node dynamically")
