trace: do dma trace when CONFIG_DMA_TRACE is selected 

CONFIG_DMA_TRACE is selected by default. But we should
not do dma trace when CONFIG_DMA_TRACE is not selected
(--disable-dma-trace is added to configure command line),
here add this judgement to fix compiling issue for that
dma trace is not selected.
