A link property can be set during creation, with
object_property_add_link() and later with object_property_set_link().
add_link() doesn't add a reference to the target object, while
set_link() does.
Furthemore, OBJ_PROP_LINK_UNREF_ON_RELEASE flags, set during add_link,
says whether a reference must be released when the property is destroyed.
This can lead to leaks if the property was later set_link(), as the
added reference is never released.
Instead, rename OBJ_PROP_LINK_UNREF_ON_RELEASE to OBJ_PROP_LINK_STRONG
and use that has an indication on how the link handle reference
management in set_link().

Coverity found that the string return by 'object_get_canonical_path' was not
being freed at two locations in the model (CID 1391294 and CID 1391293) and
also that a memset was being called with a value greater than the max of a byte
on the second argument (CID 1391286). This patch corrects this by adding the
freeing of the strings and also changing to memset to zero instead on
descriptor unaligned errors.
