Subject: drm/amdgpu: clear err_event_athub flag after reset exit
Git-commit: 00eaa57172a02edddbf445112409e807e0caacd9
Patch-mainline: v5.6-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
Otherwise next err_event_athub error cannot call gpu reset. And following
resume sequence will not be affected by this flag.
