[PATCH 1/2] drm/amd/ras: tell KFD the reset came from an ECC error

[Xiang Liu <xiang.liu@amd.com>]

kfd_signal_reset_event() picks between KFD_HW_EXCEPTION_ECC and
KFD_HW_EXCEPTION_GPU_HANG from the SRAM ECC flag, and only delivers the
memory exception event for the former. Nothing raises that flag on the
RAS module paths, so a reset caused by an uncorrectable or a consumed
poison error is reported to every process on the device as a plain hang
and the runtime carries on instead of tearing the workload down.

Raise it the way the per IP callbacks used to.
