The etnaviv devcoredump is created in the GPU reset path, which
must make forward progress to avoid stalling memory reclaim on
unsignalled dma fences. The currently used __GFP_NORETRY does not
prohibit sleeping on direct reclaim, breaking the forward progress
guarantee. Switch to GFP_NOWAIT, which allows background reclaim
to be triggered, but avoids any stalls waiting for direct reclaim.
