ore: Make ore_striping_info and ore_calc_stripe_info public
The struct ore_striping_info will be used later in other structures. And ore_calc_stripe_info as well. Rename them make struct ore_striping_info public. ore_calc_stripe_info is still static, will be made public on first use. Signed-off-by: Boaz Harrosh <bharrosh@panasas.com>
