test_objagg: Uninitialized variable in error handling
We need to set the error message on this path otherwise some of the
callers, such as test_hints_case(), print from an uninitialized pointer.
We had a similar bug earlier and set "errmsg" to NULL in the caller,
test_delta_action_item(). That code is no longer required so I have
removed it.
Fixes: 9069a3817d82 ("lib: objagg: implement optimization hints assembly and use hints for object creation")
