XEN: Grant table address, xen_hvm_resume_frames, is a phys_addr not a pfn
From: Eric Trudeau <etrudeau@broadcom.com>
xen_hvm_resume_frames stores the physical address of the grant table.
englighten.c was incorrectly setting it as if it was a page frame number.
This caused the table to be mapped into the guest at an unexpected physical
address.
Additionally, a warning is improved to include the grant table address which
failed in xen_remap.
