[libvirt] [PATCH v1 06/21] util: eventpoll: use VIR_AUTOFREE instead of VIR_FREE for scalar types

[Sukrit Bhatnagar]

By making use of the GCC's __attribute__((cleanup)) handled by VIR_AUTOFREE
macro, majority of the VIR_FREE calls can be dropped, which in turn leads to
getting rid of most of our cleanup sections.
