Rollback of FD sets passed to qemu is also needed after possible restart of libvirtd when we need to serialize the data into status XML. For this purpose we need to access the fdset ID once it was passed to qemu and potentially re-create a 'qemuFDPass' struct in passed state. Introduce 'qemuFDPassNewPassed' and 'qemuFDPassIsPassed'.
