For ZBC devices I/O must not cross zone boundaries, so setup
the 'chunk_sectors' block queue setting to the zone size.
This is only valid for REPORT ZONES SAME type 2 or 3;
for other types the zone sizes might be different
for individual zones. So issue a warning if the type is
found to be different.
Also the capacity might be different from the announced
capacity, so adjust it as needed.
