The qemu_create_display_surface_guestmem() function was added in
commit a77549b3ffcc24c32ee4e but apparently never used. Remove it.

(The API of this function is in any case awkward as a generic
function: it assumes that a physical address uniquely identifies
a piece of memory in the system, which is mostly but not
always true.)
