When preparing a memcpy operation, if the kernel fails to allocate memory for a link descriptor after the first link descriptor has already been allocated, then some memory will never be released. Fix the problem by walking the list of allocated descriptors backwards, and freeing the allocated descriptors back into the DMA pool. Signed-off-by: Ira W.
