dmaengine: ae4dma: Use the MSI count and its corresponding IRQ number
[ Upstream commit feba04e6fdf4daccc83fc09d499a3e32c178edb4 ]
Instead of using the defined maximum hardware queue, which can lead to
incorrect values if the counts mismatch, use the exact supported MSI
count and its corresponding IRQ number.
