Oops, right, C&P mistake. I removed it.

dma_alloc_coherent generates the same dump as kzalloc on ENOMEM, I
guessed the intention was to add extra logging on the high order
allocations, but this allocation is larger than the dma one and
doesn't get a print so <shrug>

I was tempted to remove those prints too..

Thanks,
