i965/vec4: Override destination register writemask in sampler message send.
This line was removed by accident in commit 16b911257440afbd77a6eb762e28df62e3c19bc7 causing a regression in the ES3-CTS.gtf.GL3Tests.shadow.shadow_execution_vert Khronos conformance test. It's necessary because the swizzle_result() code below expects all four components of the vector to be valid.
