Honestly, I'm thinking about dropping the check.
It often works without any init because the stage 3 bootloader does an
init and we do not check the print functions for errors.

It's best effort at this point :)
I'm more concerned with interrupts that print things while a printf
holds the sclp_busy lock. But that mostly happens if you mess up a sclp
call.
