Michael Roth e8bbd303d7 x86/fault: Dump RMP table information when RMP page faults occur
RMP faults on kernel addresses are fatal and should never happen in
practice. They indicate a bug in the host kernel somewhere. Userspace
RMP faults shouldn't occur either, since even for VMs the memory used
for private pages is handled by guest_memfd and by design is not
mappable by userspace.

Dump RMP table information about the PFN corresponding to the faulting
HVA to help diagnose any issues of this sort when show_fault_oops() is
triggered by an RMP fault.
