[SCSI] fix up short inquiry printing

A recent drivers base commit:

3e95637a

Caused the bus to be added to dev_printk, so now our SCSI inquiry short
messages print like this:

scsiscsi 2:0:0:0: Direct access     IBM-ESXS ST973401SS       B519 PQ: 0 ANSI: 5

Just remove the "scsi" from the sdev_printk to compensate.
