i965: Fix the response len of masked sampler messages for 8-wide dispatch.

The bad response length would hang the GPU with a masked sample in a
shader using control flow.  For 8-wide, the response length is always
4, and masked slots are just not written to.  brw_wm_glsl.c already
allocates registers in the right locations.

Fixes piglit glsl-fs-bug25902 (fd.o bug #25902).
