[SCSI] qla2xxx: Correct display of ISP serial-number.
The original serial-number calculations based on WWPN no longer apply to newer ISPs (ISP24xx and ISP25xx). These newer board's serial number reside in the VPD. Signed-off-by: Andrew Vasquez <andrew.vasquez@qlogic.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
