Halil Pasic 0a01e082a4 s390/ipl: sync back loadparm 
We expose loadparm as a r/w machine property, but if loadparm is set by
the guest via DIAG 308, we don't update the property. Having a
disconnect between the guest view and the QEMU property is not nice in
itself, but things get even worse for SCSI, where under certain
circumstances (see 789b5a401b "s390: Ensure IPL from SCSI works as
expected" for details) we call s390_gen_initial_iplb() on resets
effectively overwriting the guest/user supplied loadparm with the stale
value.
