dm raid: fix random optimal_io_size for raid0

Browse source

raid_io_hints() was retrieving the number of data stripes used for the
calculation of io_opt from struct r5conf, which is not defined for raid0
mappings.

Base the calculation on the in-core raid_set structure instead.

Also, adjust to use to_bytes() for the sector -> bytes conversion
throughout.
