i965/blorp: Fix clear code for ignoring colormask for XRGB formats on Gen9+

Browse source 
This is equivalent of 73b01e2711
for blorp.

v2 (Ken): No need to call _mesa_format_has_color_component() now
          that the number of components is gotten from
          _mesa_base_format_component_count().
