We could easily get rid of printk_[stack_]address() by just inlining
it into the callers, and make them use the [<%p[SB]>] thing directly.

That's a separate issue from trying to get rid of the hex parts of the
address, though.

Also, note that even if you merged printk_stack_address into its
callers, you'd still have the actual stack walking ->address() and
->stack() calls as separate calls, so it's not like you'd really avoid
any interleaving if there are concurrent walkers.
