Frank Li 71a77ab76e net: allwinner: remove dmaengine_desc_free() 
dmaengine_desc_free() is designed for DMA_CTRL_REUSE. If DMA_CTRL_REUSE
is not set, dmaengine_desc_free() will return -EPERM.

	if (!dmaengine_desc_test_reuse(desc))
		return -EPERM;

So calling dmaengine_desc_free() does nothing.
dmaengine_terminate_(a)sync() will free all already allocated descriptors.
