[PATCH] telemetry: fix potential connection issue

[Zhichao Zeng <zhichaox.zeng@intel.com>]

For calling memcpy when the source and destination addresses are the same,
there is a small probability that there will be a copy error issue in some
environments, resulting in a failure to connect.

This patch uses memmove instead of memcpy to avoid this issue.
