pg_dump: Set private_date pointer to NULL in callback

The end callback for ZStandard compression frees the private_data
but didn't set the pointer to NULL after freeing.  This is not a
bug as the code is right now, since nothing is dereferencing the
pointer upon returning from the callback but it is good practice
to do.
