dmaengine: stm32-dma: remove unused ‘dst_addr’
In stm32_dma_set_xfer_param(), variable ‘dst_addr’ is initialized but never used, which leads to warning with W=1 drivers/dma/stm32-dma.c: In function ‘stm32_dma_set_xfer_param’: drivers/dma/stm32-dma.c:577:23: warning: variable ‘dst_addr’ set but not used [-Wunused-but-set-variable] dma_addr_t src_addr, dst_addr; So remove it.
