of: property: decrement node refcount in of_fwnode_get_reference_args()
[ Upstream commit 60d865bd5a9b15a3961eb1c08bd4155682a3c81e ]
In of_fwnode_get_reference_args(), the refcount of of_args.np has
been incremented in the case of successful return from
of_parse_phandle_with_args() or of_parse_phandle_with_fixed_args().
Decrement the refcount if of_args is not returned to the caller of
of_fwnode_get_reference_args().
Fixes: 3e3119d3088f ("device property: Introduce fwnode_property_get_reference_args")
