Some Hyper-V hosts are known for ignoring SPC-2/3/4 requirement for 'INQUIRY data (see table ...) shall contain at least 36 bytes'. As a result we get tons on 'scsi 0:7:1:1: scsi scan: INQUIRY result too short (5), using 36' messages on console. As Hyper-V is also known for its serial port being extremely slow multi-VCPU guests we get CPU blocked putting these (useless) messages on console (e.g. happens when we add multiple disks). Move them to debug level.
