[Intel-gfx] [PATCH i-g-t v3] tests/gem_reset_stats: Fix retrieval of hangcheck stats expectation

[Antonio Argenziano]

The test expected IOCTL 'I915_GET_RESET_STATS' would return an error
when not root. That is no longer true in the driver since commit
4c9c0d09741d ("drm/i915: Fix retrieval of hangcheck stats") and therefore
the test was incorrectly failing.

v2:
	- Add the commit that changed the behaviour in the Driver to the
	  commit message. (Michel)

v3:
	- Reuse get_reset_count instead of implementing a new function.
	  (Michel)
