dmaengine: altera-msgdma: initialize state before requesting IRQ
msgdma_probe() registers the IRQ before initializing the tasklet, lock,
and descriptor lists used by the interrupt handler. A pending interrupt
can access incomplete state during probe.
Initialize the handler state before requesting the IRQ so the interrupt
path observes ready software state.
