When verify option is specified together with zonemode=zbd and
zone_reset_threshold option, zone reset happens to zones not full. This
erases data for verify and causes verify failure. Current implementation
avoids this scenario by assert.
To allow zone_reset_threshold option together with zonemode=zbd and
verify option, do verify before the zone reset. When zone reset is
required to an open zone with verify data, call get_next_verify() to
get verify read unit and return it from zbd_adjust_block().
