I think the better approach is to:
a) branch out at a very high level to the zoned code in
flush_scrub_stripes, or in fact even higher given that we
don't really care about tracking stripes. The write
side of scrub has to work at a zone, not stripe level for
zoned devices
b) don't create a new relocation thread per zone, but run it from
the scrub context.
