qxl-wddm-dod: Fix unmapping of physical memory

https://bugzilla.redhat.com/show_bug.cgi?id=1454866
Due to wrong addresses passed to class driver, it never does
unmapping of physical memory, causing a leak of virtual address range.
On x86 systems the device fails to start due to failure to
map physical memory range after 10-50 cycles of disable-enable.
