Do not hash userspace addresses in fault handlers
The hashing of %p was designed to restrict kernel addresses. There is
no reason to hash the userspace values seen during a segfault report,
so switch these to %px. (Some architectures already use %lx.)
Fixes: ad67b74d2469d9b8 ("printk: hash addresses printed with %p")
