mesa: fix non-trivial designated initializers issue

From: Kai Kang <kai.kang@windriver.com>

It fails to compile intel/compiler/brw_simd_selection.cpp with g++ 7.5.0:

| mesa-23.0.0/src/intel/compiler/brw_simd_selection.cpp: In function ‘int
  brw_simd_select_for_workgroup_size(const intel_device_info*,
  const brw_cs_prog_data*, const unsigned int*)’:
| mesa-23.0.0/src/intel/compiler/brw_simd_selection.cpp:205:7: sorry,
  unimplemented: non-trivial designated initializers not supported
|        };
|        ^

Initialize the leading 2 members to fix the issue.

Mesa officially needs GCC 8.0.0 or later.

There is feedback upstream suggesting this causes a memory leak?
