module: remove module_text_address()
Impact: Replace and remove risky (non-EXPORTed) API
module_text_address() returns a pointer to the module, which given locking
improvements in module.c, is useless except to test for NULL:
1) If the module can't go away, use __module_text_address.
2) Otherwise, just use is_module_text_address().
