[libvirt] [PATCH v2 20/35] util: netdevmacvlan: use VIR_AUTOFREE instead of VIR_FREE for scalar types

By making use of GNU C's cleanup attribute handled by the VIR_AUTOFREE macro for declaring scalar variables, majority of the VIR_FREE calls can be dropped, which in turn leads to getting rid of most of our cleanup sections.
