[SCSI] sym53c8xx: Make interrupt handler capable of returning IRQ_NONE
After this happens, the kernel disables the IRQ, causing the SCSI card
to stop working until the next reboot. The problem is caused by the
interrupt handler returning IRQ_NONE instead of IRQ_HANDLED after
handling an interrupt-on-the-fly (INTF) condition. The following patch
fixes the problem.
