msm: camera: isp: Add SFE core idx in CSID error notify

It's possible that for a given use-case the pipeline is
CSID2->SFE0->IFE2, in the event of an overflow we need to log
the right SFE's debug registers. Unlike IFE we cannot use
CSID hw_idx to find the SFE core in the pipeline. The change
ensures we log the connected SFE core's debug registers.
