dmaengine: edma: fixed wrongly initialized data parameter to the edma callback

Browse Source 
The "data" parameter passed indirectly to the edma_callback() should be
edma_chan and not the dma_chan.

This bug was so far harmless since the offset of struct dma_chan within struct
edma_chan is 0. However as soon as someone changes struct edma_chan this would
cause troubles.
