Coverity reports a possible buffer overrun due to a non-NUL-terminated
string in scsi_property_set_loadparm(). While things are not so easy,
because qdev_prop_sanitize_s390x_loadparm is designed to operate on a
buffer that is not NUL-terminated, in this case the string *does* have
to be NUL-terminated because it is read by scsi_property_get_loadparm
and s390_build_iplb.
