nv30: Fix creation of scanout buffers
Scanout buffers on nv30 must always be non-swizzled and have special
width alignment constraints.
These constrains have been taken from the xf86-video-nouveau
src/nv_accel_common.c: nouveau_allocate_surface() function.
nouveau_allocate_surface() applies these width constraints only when a
tiled attribute is set, which it sets for all surfaces allocated via
dri, and this "tiling" is not the same as swizzling, scanout surfaces
must be linear / have a uniform_pitch or only complete garbage is shown.
This commit fixes dri3 on nv30 showing a garbled display, with dri3 the
scanout buffers are allocated by mesa, rather then by the ddx, and the
wrong stride of these buffers was causing the garbled display.
