powerpc/traps: Fix the message printed when stack overflows

Browse Source 
commit 9bf3d3c4e4fd82c7174f4856df372ab2a71005b9 upstream.

Today's message is useless:

  [   42.253267] Kernel stack overflow in process (ptrval), r1=c65500b0

This patch fixes it:

  [   66.905235] Kernel stack overflow in process sh[356], r1=c65560b0

Fixes: ad67b74d2469 ("printk: hash addresses printed with %p")
