Subject: scsi_id: sending ioctl 2285 to a partition

Commit 0bfc96cb77 adds this printk that triggers tens of thousands of
times during a run of "a well-known database benchmark".  0x2285 is SG_IO.
I'm not sure why scsi_id feels that it needs to repeatedly send a SCSI
INQUIRY to a partition, but there we are.

Oh, userspace is RHEL 6.2 and the kernel in use is 3.2.3.
