[PATCH xf86-video-ati] Use correct tiling in drmmode_create_bo_pixmap

[Ryan Kennedy]

The callers were using 0 for the tiling flags, causing surfaces to be
incorrectly treated as linear. This issue was causing corruption on Cayman
just after login with GNOME3. The kernel was rejecting the cs in
drmmode_copy_fb due to invalid texture pitch.
