i915: reset swrast state after calling swrast DrawPixels.

In order to optimize DrawPixels, the i915 texenv program isn't
applied to swrast DrawPixels in the i915 driver. This causes this
program isn't applied to any following swrast functions. Resetting
the swrast state fixes this issue.  Fix #13614
