x86/mm: Delete disabled debug code

This code doesn't run. Since 2008:

  4f9c11dd49fb ("x86, 64-bit: adjust mapping of physical pagetables to work with Xen")

the kernel has gained more flexible logging and tracing capabilities;
presumably if anyone wanted to take advantage of this log message they would
have got rid of the "if (0)" so they could use these capabilities.

Since they haven't, just delete it.
