[PATCH 2/4] qemu: domain: Add macro to simplify access to vm private data

[Peter Krempa <pkrempa@xxxxxxxxxx>]

Sometimes adding a separate variable to access vm->privateData is not
necessary. Add a macro that will do the typecasting rather than having
to add a temp variable to force the compiler to typecast it.
