Matthew Brost 0f9d36af8f drm/i915: Fix possible uninitialized variable in parallel extension 
'prev_engine' was declared inside the output loop and checked in the
inner after at least 1 pass of either loop. The variable should be
declared outside both loops as it needs to be persistent across the
entire loop structure.
