i965/gen10: Change the order of PIPE_CONTROL and load register.
I believe the workaround describes that the MI_LOAD_REGISTER_IMM should
come right after the 3DSTATE_SAMPLE_PATTERN.
This fixes GPU hangs in the i965 initial state batchbuffer when running
some Piglit tests with always_flush_batch=true.
