6pack: remove global strings

They are __init, so they are freed after init is done. But this
obfuscates the code.

Provided these days, we usually don't print anything if everything has
gone fine, drop the info print completely (along with now unused and
always artificial SIXPACK_VERSION).

And move the other string into the printk proper (while converting from
KERN_ERR to pr_err()).
