dmaengine: sun4i: use 'linear_mode' in sun4i_dma_prep_dma_cyclic
drivers/dma/sun4i-dma.c: In function sun4i_dma_prep_dma_cyclic:
drivers/dma/sun4i-dma.c:672:24: warning:
variable linear_mode set but not used [-Wunused-but-set-variable]
commit ffc079a4accc ("dmaengine: sun4i: Add support for cyclic requests with dedicated DMA")
involved this, explicitly using the value makes the code more readable.
