[PATCH driver/intel] In sna_pixmap_alloc_gpu() process user selected tiling thru kgem_choose_tiling()

[Egbert Eich]

From: Egbert Eich <eich at suse.de>

In sna_pixmap_alloc_gpu() a different than the default tiling may be picked
by a usage hint. Before passing the tiling to kgem_create_2d() fix it up
by calling kgem_choose_tiling(). This avoids kgem_surface_size() not being able
to find a surface size for the tiling value.
