Only try and read a VMDescription if it should be there

The VMDescription section maybe after the EOF mark, the current code
does a 'qemu_get_byte' and either gets the header byte identifying the
description or an error (which it ignores).  Doing the 'get' upsets
RDMA which hangs on old machine types without the VMDescription.

Just avoid reading the VMDescription if we wouldn't send it.
