[SCSI] qla2xxx: Simplify interrupt handler locking.

There's no need to use the heavier (albiet safer)
*_irq[save|restore]() locking primitives within the driver's
interrupt handlers, interrupts are guaranteed to be
non-reentrant.  Use lightweight spin_lock() and spin_unlock()
primitives while acquiring the hardware_lock.
