As one of its arguments, the
virQEMUCapsProbeFullDeprecatedProperties() gets a pointer to
GStrv (a string list), which it may eventually replace. It's
single caller (virQEMUCapsProbeQMPHostCPU()) passes a string list
indeed. Now, when replacing one string list with another plain
g_free() is not enough as we need to free individual strings too.
