x86/mm: Don't leak kernel addresses

Since commit:

  ad67b74d2469d9b8 ("printk: hash addresses printed with %p")

at boot "____ptrval____" is printed instead of actual addresses:

    found SMP MP-table at [mem 0x000f5cc0-0x000f5ccf] mapped at [(____ptrval____)]

Instead of changing the print to "%px", and leaking a kernel addresses,
just remove the print completely, like in:

  071929dbdd865f77 ("arm64: Stop printing the virtual memory layout").
