Matthew Auld 75353bcd21 drm/i915: clear the shadow batch 
The shadow batch is an internal object, which doesn't have any page
clearing, and since the batch_len can be smaller than the object, we
should take care to clear it.

Testcase: igt/gen9_exec_parse/shadow-peek
Fixes: 4f7af1948a ("drm/i915: Support ro ppgtt mapped cmdparser shadow buffers")
