Fix call back free problem. 

This is copied from the development branch. The issue is that calling
vpi_free_object should not really free a call back handle since it is
the real call back object and doing so will invalidate it. This will
likely end with a core dump.

/*
* The vpi_free_object() call to a callback doesn't actually delete
* anything, we instead allow the object to run its course and delete
* itself. The semantics of vpi_free_object for a callback is that it
* deletes the *handle*, and not the object itself, so given the vvp
* implementation, there is nothing to do here.
