Oleksandr Andrushchenko 24ded292a5 drm/xen-front: Fix mmap attributes for display buffers
When GEM backing storage is allocated those are normal pages,
so there is no point using pgprot_writecombine while mmaping.
This fixes mismatch of buffer pages' memory attributes between
the frontend and backend which may cause screen artifacts.

Fixes: c575b7eeb8 ("drm/xen-front: Add support for Xen PV display frontend")
