  Smatch complains that these are not initialized if get_cntl_version()
fails but we still print them in the debug message.  Not the end of
the world, but true enough.  Let's just initialize them to a dummy value
to make the checker happy.

Thanks for the cleanup.

Could use a fixes tag, and also I'd prefer to maintain the style of 
sorting the variable declaration lines by line length.  Given the minor 
nature of these nits, I plan to address them.

The fixes tag thing could have gone either way.  It's really minor.

I agree with Jeff's comment to sort the variable declaration length wise.
