From: Alex Dai <yu....@intel.com>
We keep a copy of GuC fw in a GEM obj. However its content is lost
if the GEM obj is swapped (igt/gem_evict_*). Therefore, the later
fw loading during GPU reset will fail. Mark the obj dirty after
copying data into the pages. So its content will be kept during
swapped out.
