Coverity notes that the result of object_dynamic_cast() to
SCSIDevice is not checked in s390_gen_initial_iplp(); as
we know that we always have a SCSIDevice in that branch,
we can instead cast via SCSI_DEVICE directly.

Coverity: CID 1401098
Fixes: 44445d8668f4 ("s390 vfio-ccw: Add bootindex property and IPLB data")
