[i915] Push locking in intelClearWithTris down inside meta_draw_poly.

The lock coverage and checks for cliprects were unneeded since the batchbuffer
will have INTEL_BATCH_CLIPRECTS anyway.  It appeared to be a leftover from
intelClearWithBlit.

This makes the locking requirements of i915 meta_draw_quad match i965
meta_draw_quad.
