Christoph Hellwig b35243a447 block: rework bio splitting ...

The current setup with bio_may_exceed_limit and __bio_split_to_limits
is a bit of a mess.

Change it so that __bio_split_to_limits does all the work and is just
a variant of bio_split_to_limits that returns nr_segs.  This is done
by inlining it and instead have the various bio_split_* helpers directly
submit the potentially split bios.

To support btrfs, the rw version has a lower level helper split out
that just returns the offset to split.  This turns out to nicely clean
up the btrfs flow as well.
