Previous commit for interrupt mitigation moved the done interrupt
acknowlegement from the isr to the talitos_done tasklet.
This patch moves the done interrupt acknowledgement back
into the isr so that done interrupts will always be acknowledged.
This covers the case for acknowledging interrupts for channel done processing
that has actually already been completed by the tasklet prior to fielding
a pending interrupt.
