[SCSI] ipr: Fixup device type check
Fixup a check used by the ipr driver to determine if a given device is a SCSI disk. Due to the addition of support for attaching SATA devices, this check needs to be more robust. Signed-off-by: Brian King <brking@us.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
