[libvirt] [PATCH 3/3] virBuffer: Try harder to free buffer

[Michal Privoznik]

Currently, the way virBufferFreeAndReset() works is it relies on
virBufferContentAndReset() to fetch the buffer content which is
then freed. This works as long as there is no bug in virBuffer*
implementation (not true apparently). Explicitly call free() over
buffer content.
