dmaengine: fsl-edma: cleanup chan after dma_async_device_unregister
There is kernel dump when do module test:
sysfs: cannot create duplicate filename
/devices/platform/soc@0/44000000.bus/44000000.dma-controller/dma/dma0chan0
__dma_async_device_channel_register+0x128/0x19c
dma_async_device_register+0x150/0x454
fsl_edma_probe+0x6cc/0x8a0
platform_probe+0x68/0xc8
fsl_edma_cleanup_vchan will unlink vchan.chan.device_node, while
dma_async_device_unregister needs the link to do
__dma_async_device_channel_unregister. So need move fsl_edma_cleanup_vchan
after dma_async_device_unregister to make sure channel could be freed.
So clean up chan after dma_async_device_unregister to address this.
