drm/radeon: fix double free in radeon_gpu_reset
radeon_ring_restore is freeing the memory for the saved ring data. We need to remember that, otherwise we try to restore the ring data again on the next try. Additional to that it shouldn't try the reset infinitely if we have saved ring data. Signed-off-by: Christian König <deathsimple@vodafone.de> Reviewed-by: Alex Deucher <alexander.deucher@amd.com>
