tree: Change signature of extract_programmer_param_str()

Results can be reproduced with the following invocation;
```
 $ find -name '*.c' -exec sed -i 's/extract_programmer_param_str(/extract_programmer_param_str(NULL, /g' '{}' \;
```

This allows for a pointer to the actual programmer parameters
to be passed instead of a global.
