Alexander.Barabash@dell.com 10d55ea613 ioat: ioat_alloc_ring() failure handling. 
[ Upstream commit b0b5ce1010ffc50015eaec72b0028aaae3f526bb ]

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.
