dma: fsl-edma: fix static checker warning of NULL dereference
The static checker reports following warning:
drivers/dma/fsl-edma.c:732 fsl_edma_xlate()
error: we previously assumed 'chan' could be null (see line 737)
The changes of the loop cursor in the iteration may result in
NULL dereference when dma_get_slave_channel failed but loop
will continue. So use list_for_each_entry_safe() instead of
list_for_each_entry() to against this.
