[libvirt] [PATCH v2 11/41] util: mdev: define cleanup function using VIR_DEFINE_AUTOPTR_FUNC

[Sukrit Bhatnagar]

Using the new VIR_DEFINE_AUTOPTR_FUNC macro defined in
src/util/viralloc.h, define a new wrapper around an existing
cleanup function which will be called when a variable declared
with VIR_AUTOPTR macro goes out of scope. Also, drop the redundant
viralloc.h include, since that has moved from the source module into
the header.

When variables of type virMediatedDevicePtr and virMediatedDeviceTypePtr
are declared using VIR_AUTOPTR, the functions virMediatedDeviceFree
and virMediatedDeviceTypeFree, respectively, will be run automatically
on them when they go out of scope.
