[PATCH] scsi_scan: move 'INQUIRY result too short' message to debug level

[Vitaly Kuznetsov]

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.
