Clang warns:

  drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_packet_manager_v9.c:267:3:
  error: implicit conversion from enumeration type 'enum
  mes_map_queues_extended_engine_sel_enum' to different enumeration type
  'enum mes_unmap_queues_extended_engine_sel_enum'
  [-Werror,-Wenum-conversion]

                  ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  1 error generated.

Use 'extended_engine_sel__mes_unmap_queues__sdma0_to_7_sel' to eliminate
the warning, which is the same numeric value of the proper type.

Fixes: 009e9a15 ("drm/amdkfd: navi2x requires extended engines to map and unmap sdma queues")
