pc-bios/s390x: Initialize machine loadparm before probing IPL devices
Commit bb185de423 ("s390x: Add individual loadparm assignment to
CCW device") allowed boot devices to be assigned a loadparm value independent
of the machine value, however, when no boot devices are defined, the machine
loadparm becomes ignored. Therefore, let's check the machine loadparm
prior to probing the devices.
