[PATCH 9/9] util: Avoid using wrong free function

[John Ferlan <jferlan@xxxxxxxxxx>]

Since 1e2ae2e31, changes to use the automagic free logic didn't take
into account that one path uses posix_memalign and the other uses
VIR_ALLOC_N - the former requires using VIR_FREE() and not g_free()
to free the memory.

Found by Coverity.
