Chris Wilson 5948938700 drm/i915/gt: Add a safety submission flush in the heartbeat 
Just in case everything fails (like for example "missed interrupt
syndrome" on Sandybridge), always flush the submission tasklet from the
heartbeat. This papers over such issues, but will still appear as a
second long glitch, and prevents us from detecting it unless we happen
to be performing a timed test.

v2: We rely on flush_submission() synchronizing with the tasklet on
another CPU.
