[libvirt] [PATCH v2 23/41] util: usb: define cleanup function using VIR_DEFINE_AUTOPTR_FUNC

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 a variable of type virUSBDevicePtr is declared using VIR_AUTOPTR, the function virUSBDeviceFree will be run automatically on it when it goes out of scope.
