[SCSI] qla2xxx: locking problem in qla2x00_init_rings()
IRQs are already disabled here so we don't need to disable them again.
But more importantly, the spin_lock_irqsave() overwrites "flags" and
that breaks things when we want to re-enable the IRQs when we call
spin_unlock_irqrestore(&ha->hardware_lock, flags);
