llvmpipe: clamp color storage for integer types.

If storing to an integer for lower bit size (i.e. 16-bit uint to
10-bit uint), we need to clamp to the maximum value not truncate.

Fixes:
dEQP-VK.api.copy_and_blit.core.blit_image.all_formats.color.r16_uint.a2b10g10r10_uint_pack32.optimal_optimal_nearest
