Ensure that the rc code is set when attempting to register a hw_breakpoint
The setup code for the hw_breakpoint doesn't check the return code. The problem
occurs later when there is an attempt to unregister the invalid hw_breakpoint.
This makes sure that rc gets propogated to minize the possibility of later
problems.
