Subject: [RFC PATCH] tools/power turbostat: Fix caller parameter of get_tdp_amd()

Commit 9392bd98bba760be96ee ("tools/power turbostat: Add support for AMD
Fam 17h (Zen) RAPL") add a function get_tdp_amd(), the parameter is CPU
family. But the rapl_probe_amd() function use wrong model parameter.
Fix the wrong caller parameter of get_tdp_amd() to use family.
