bus: omap_l3_noc: Correct returning IRQ_HANDLED unconditionally in the irq handler

commit c4cf0935 upstream.

Correct returning IRQ_HANDLED unconditionally in the irq handler.
Return IRQ_NONE for some interrupt which we do not expect to be
handled in this handler. This prevents kernel stalling with back
to back spurious interrupts.

Fixes: 2722e56d ("OMAP4: l3: Introduce l3-interconnect error handling driver")
