In a lot of places we want to know the DMA direction for a given
struct request.  Add a little helper to make it a littler easier.

You introuduce the helper here but you're using it in 8/15 for the 1st time.

Could you convert the possible users to use the new helper in this patch
as well?

I'd rather not throw that into a nvme series.  Those are easily cleanups
for later.  Maybe we can even encourage people that would otherwise
do whitespace cleanups or incorrect refcount_t conversions to take care
of it :)
