qom: Add check() argument to object_property_add_link()
There are currently three types of object_property_add_link() callers:
1. The link property may be set at any time.
2. The link property of a DeviceState instance may only be set before
realize.
3. The link property may never be set, it is read-only.
Something similar can already be achieved with
object_property_add_str()'s set() argument. Follow its example and add
a check() argument to object_property_add_link().
Also provide default check() functions for case #1 and #2. Case #3 is
covered by passing a NULL function pointer.
