Fix test_scan_layouts[True-1-src_layout10-64-32] on LTS driver; ignoring loadBinary error with large registers (#2808)

I think if there is at least one working combination, we can avoid
raising an exception. I left the output of the message about this
problem so that we could see such things and gradually fix them.
