iris: Initialize ice->state.prim_mode to an invalid value

Browse source 
It was calloc'd to 0 which is PIPE_PRIM_POINTS, which means that we
fail to notice an initial primitive of points being new, and fail at
updating the "primitive is points or lines" field.

We do not need to reset this on device loss because we're tracking
the last primitive mode sent to us on the CPU via draw_vbo, not the
last primitive mode sent to the GPU.

Fixes several tests:
- dEQP-GLES3.functional.clipping.point.wide_point_clip
- dEQP-GLES3.functional.clipping.point.wide_point_clip_viewport_center
- dEQP-GLES3.functional.clipping.point.wide_point_clip_viewport_corner

Fixes: dcfca0af7c ("iris: Set XY Clipping correctly.")
