`dio200_pci_detach()` doesn't need to check if the pointer to constant board data (`thisboard`) and the pointer to private per-device data (`devpriv`) are valid before calling `amplc_dio200_common_detach()`. It has no further need to check `thisboard` so remove the variable altogether. Move the test of `devpriv` to the first point it is needs to be valid.
