[SCSI] arcmsr: irq handler fixes, cleanups, micro-opts

Browse Source 
* Remove IRQF_DISABLED, it is clearly wrong for this driver.

* Remove wasteful spin_lock_irqsave() in interrupt handler.
  The lighter-weight spin_lock() is all that's needed.

* Annotate with FIXME where arcmsr_interrupt() is called
  without any spinlock being acquired.

* Eliminate pointless cast from void pointer in arcmsr_do_interrupt()
