[PATCH 11/13] virQEMUCapsProbeQMPTPM: Refactor handling of string lists

[Peter Krempa <pkrempa@xxxxxxxxxx>]

This refactors multiple aspects of the function:

1) Use automatic memory freeing
2) Remove need to check element count in the returned arrays
3) Fixes questionable code linebreaks
4) Removes reuse of variables
