Subject: [PATCH] svga: increase SVGA_MAX_FRAMEBUFFER_DEFAULT_SAMPLES to 16

This fixes the piglit arb_framebuffer_no_attachments-query test
(asserted in debug builds, crashed in release builds).  Passes
with this change.

The SVGA_MAX_FRAMEBUFFER_DEFAULT_SAMPLES value is only used to
dimension the svga_rasterizer_state::altRastIds[] array.
