[PATCH 7/8] block: remove the fallback case in queue_dma_alignment

[Christoph Hellwig <hch@lst.de>]

Now that all updates go through blk_validate_limits the default of 511
is set at initialization time.  Also remove the unused NULL check as
calling this helper on a NULL queue can't happen (and doesn't make
much sense to start with).
