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.
