patch - log errors from huge fault handler

I'm still not seeing any leads for what might be the problem.  The QEMU dumps
suggest a problem handling a page fault and the original report implicates the
new huge_fault handler.  So let's log anything from the huge_fault handler that
doesn't install the pte.  Please apply this patch to your stock v6.14.4 kernel
and report the resulting dmesg after the VM crash.
