md: raid0: remove ->sectors from the strip_zone structure.
storing ->sectors is redundant as is can be computed from the difference z->zone_end - (z-1)->zone_end The one place where it is used, it is just as efficient to use a zone_end value instead. And removing it makes strip_zone smaller, so they array of these that is searched on every request has a better chance to say in cache. So discard the field and get the value from elsewhere.
