dmapool: remove checks for dev == NULL

dmapool originally tried to support pools without a device because
dma_alloc_coherent() supports allocations without a device.  But nobody
ended up using dma pools without a device, and trying to do so will result
in an oops.  So remove the checks for pool->dev == NULL since they are
unneeded bloat.
