drm: qxl: ensure surf.data is ininitialized
[ Upstream commit fbbf23ddb2a1cc0c12c9f78237d1561c24006f50 ]
The object surf is not fully initialized and the uninitialized
field surf.data is being copied by the call to qxl_bo_create
via the call to qxl_gem_object_create. Set surf.data to zero
to ensure garbage data from the stack is not being copied.
Addresses-Coverity: ("Uninitialized scalar variable")
Fixes: f64122c1f6ad ("drm: add new QXL driver. (v1.4)")
