[PATCH v3 18/25] virTypedParamsValidate: Refactor variable declaration and cleanup

[Peter Krempa]

Use automatic memory cleanup for the 'keys' and 'sorted' helpers and
remove the 'cleanup' label. Since this patch is modifying variable
declarations ensure that all declarations conform with our coding style.
