[PATCH qxl-wddm-dod] Do not take into account move operations for mapping

[Frediano Ziglio <fziglio@xxxxxxxxxx>]

This is a follow up of 31ca5d035d2b24912044ef69ff23b3b854cd72dd
("Implements screen to screen move correctly").

As now we don't copy memory to implement moves there's no
reason to take into account these area for memory mappings
as memory is not accessed anymore.
