Platforms with per-engine reset enabled (i915.reset=2) are unlikely to
perform a full chip reset, keeping the reset_count unmodified. In order
to keep the expectations of this test, enforce that full GPU reset is
enabled (i915.reset=1).
Later on, we can expand the reset_stats ioctl to also return the number
of per-engine resets and use reset_count + reset_engine_count when
checking for the updated reset count.
v2: Rebase, don't use gem_gpu_reset_type directly, since we now have
additional helpers.
