[PATCH v2 19/41] util: pci: define cleanup function using VIR_DEFINE_AUTOPTR_FUNC

[Sukrit Bhatnagar <skrtbhtngr@xxxxxxxxx>]

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 types virPCIDevicePtr, virPCIDeviceAddressPtr
and virPCIEDeviceInfoPtr are declared using VIR_AUTOPTR, the functions
virPCIDeviceFree, virPCIDeviceAddressFree and virPCIEDeviceInfoFree,
respectively, will be run automatically on them when they go out of scope.
