hw/xen: Set suppress-vmdesc for Xen machines
xen-save-devices-state doesn't currently generate a vmdesc, so restore
always triggers "Expected vmdescription section, but got 0". This is
not a problem when restore comes from a file. However, when QEMU runs
in a linux stubdom and comes over a console, EOF is not received. This
causes a delay restoring - though it does restore.
Setting suppress-vmdesc skips looking for the vmdesc during restore and
avoids the wait.
The other approach would be generate a vmdesc in qemu_save_device_state.
Since COLO shared that function, and the vmdesc is just discarded on
restore, we choose to skip it.
