hw/display/ramfb: fix guest memory un-mapping
Pulled back the `qemu_create_displaysurface_guestmem` function to create
the display surface so that the guest memory gets properly unmapped.

Log Message:
-----------
hw/display/ramfb: lock guest resolution after it's set
Only allow one resolution change per guest boot, which prevents a
crash when the guest writes garbage to the configuration space (e.g.
when rebooting).

Log Message:
-----------
hw/display/ramfb: initialize fw-config space with xres/ yres
If xres / yres were specified in QEMU command line, write them as an initial
resolution to the fw-config space on guest reset, which a later BIOS / OVMF
patch can take advantage of.
