dmaengine: altera-msgdma: use irq variant of spin_lock/unlock while invoking callbacks

[ Upstream commit 261d3a85 ]

As we first take the lock with spin_lock_irqsave in msgdma_tasklet, Lockdep
might complain about this. Inspired by commit 9558cf4a
("dmaengine: zynqmp_dma: fix lockdep warning in tasklet")
