[PATCH v3 4/5] telemetry: rename local variables

[Bruce Richardson <bruce.richardson@intel.com>]

In the newly separated out function, rename "tmp" to "buf" to have more
meaningful variable names.

When committing, this patch can be merged with the previous. I've kept
them separate for now, as it makes reviewing a lot easier.
