fsldma: Fix the DMA halt when using DMA_INTERRUPT async_tx transfer.
The DMA_INTERRUPT async_tx is a NULL transfer, thus the BCR(count register) is 0. When the transfer started with a byte count of zero, the DMA controller will triger a PE(programming error) event and halt, not a normal interrupt. I add special codes for PE event and DMA_INTERRUPT async_tx testing.
