qom/object: Use common get/set uint helpers

Browse source 
Several objects implemented their own uint property getters and setters,
despite them being straightforward (without any checks/validations on
the values themselves) and identical across objects. This makes use of
an enhanced API for object_property_add_uintXX_ptr() which offers
default setters.

Some of these setters used to update the value even if the type visit
failed (eg. because the value being set overflowed over the given type).
The new setter introduces a check for these errors, not updating the
value if an error occurred. The error is propagated.
