Building with clang, I'm seeing u_blitter.h:627:1: error: control may reach end of non-void function [-Werror,-Wreturn-type]
The util_blitter_get_color_format_for_zs() asserts for any unhandled types, so we do not expect to reach the end of the function here.
But provide a dummy return with an explicit assert above to ensure we don't hit it with any future changes to the logic.
