Subject: drm/amdgpu: only uncorrectable error needs gpu reset
Git-commit: 91ba68f8d5727adb1c17d039af34af0f8297dff3
Patch-mainline: v5.4-rc1
References: bsc#1152489
we only read error information for correctable error in interrupt
handler, gpu reset is unnecessary since there is no data lost
in correctable error
