Peter Ujfalusi 64c7b9868e dma-trace: Make dmatb and DMA_GW dma_sg persistent after first allocation 
Do not free the dmatb so that the trace code can continue collecting
information continuously in it's buffer.

We also have another memory leak (when CONFIG_DMA_GW is set) which can be
handled this way:
Every time the dma_trace_start() is called we allocate a new dma_sg. This
is fine when the dma_trace_start() is only called once right after the
DSP finished booting, but multiple calls would eventually going to lead to
OOM.

Move the dma_sg allocation at the same place where the dmatb is allocated
to make it persistent as well.
