[PATCH v3 2/3] various: Remove unnecessary OBJECT() cast

[Philippe Mathieu-Daudé <f4bug@xxxxxxxxx>]

The OBJECT() macro is defined as:

  #define OBJECT(obj) ((Object *)(obj))

Remove the unnecessary OBJECT() casts when we already know the
pointer is of Object type.

Patch created mechanically using spatch with this script:

  @@
  typedef Object;
  Object *o;
  @@
  -   OBJECT(o)
  +   o
