ioat: ioat_alloc_ring() failure handling.
If dma_alloc_coherent() returns NULL in ioat_alloc_ring(), ring
allocation must not proceed.
Until now, if the first call to dma_alloc_coherent() in
ioat_alloc_ring() returned NULL, the processing could proceed, failing
with NULL-pointer dereferencing further down the line.
