coresight: perf: Don't set the truncated flag in snapshot mode
This patch avoids setting the truncated flag when operating in snapshot mode since the trace buffer is expected to be truncated and discontinuous from one snapshot to another. Moreover when the truncated flag is set the perf core stops enabling the event, waiting for user space to consume the data. In snapshot mode this is clearly not what we want since it results in stale data.
