powerpc/traps: Fix the message printed when stack overflows
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")
