[SCSI] qla2xxx: Remove redundant call to pci_unmap_sg().
In a corner-case failure where the request-q does not contain enough entries for a given request, pci_unmap_sg() would be called twice. Remove direct call and let the failure-path logic handle the unmapping. Signed-off-by: Andrew Vasquez <andrew.vasquez@qlogic.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
