[PATCH] dma: Revert "make dma pool to use kmalloc_node"

[Christian König]

This reverts commit 2618c60b8b5836b73e8deb385a036820744d256d.

While working myself into the dmapool code I've found this little odd
kmalloc_node().

What basically happens here is that we allocate the housekeeping structure
on the numa node where the device is attached to. Since the device is never
doing DMA to or from that memory this doesn't seem to make sense at all.

So while this doesn't seem to cause much harm it's probably cleaner to
revert the change for consistency.
