[Mesa-dev] [PATCH] intel/compiler/icl: Use invocation id bits 22:16 instead of 23:17

[Topi Pohjolainen]

Identifier bits in the dispatch header have changed. See Bspec:

SINGLE_PATCH Payload:

3D Pipeline Stages - 3D Pipeline Geometry -
Hull Shader (HS) Stage IVB+ - Payloads IVB+

Fixes: KHR-GL46.tessellation_shader.tessellation_shader_tc_barriers.barrier_guarded_read_write_calls
