If pool creation\nfails, probe still continues with DMA setup, algorithm registration and\nchild population even though later request setup depends on that pool.\n\nStop probing when sa_init_mem() fails, and route that failure to the PM\ncleanup path without attempting to destroy an uncreated DMA pool."
