New subject: [PATCH 4/7] qemuFDPassTransferCommand: Mark that FD was passed
Until now the code didn't expect that we'd want to rollback/detach a FD
passed on the commandline, but whith disk backend FD passing this can
happen.
Properly mark the 'qemuFDPass' object as passed to qemu even when it was
done on the commandline.

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'.
