w32: Make qemu_vfree() accept NULL like the POSIX implementation
On POSIX, qemu_vfree() accepts NULL, because it's merely wrapper
around free(). As far as I can tell, the Windows implementation
doesn't. Breeds bugs that bite only under Windows.
Make the Windows implementation behave like the POSIX implementation.
