dmaengine: ioat: fixing the wrong dma_dev->chancnt
The chancnt would be updated in __dma_async_device_channel_register(),
but it was assigned in ioat_enumerate_channels(). Therefore chancnt has
the wrong value.
Add chancnt member to the struct ioatdma_device, ioat_dma->chancnt
is used in ioat, dma_dev->chancnt is used in dmaengine.
