[PATCH] zbd: remove reset_zone flag from fio_zone_info

[Dmitry Fomichev <dmitry.fomichev@xxxxxxx>]

The reset_zone flag that is defined in fio_zone_info structure is
only referenced in zbd_adjust_block() function. Convert this flag
to a local variable and save some room in zbd_info array which can
be pretty large when running fio against high capacity zoned devices.
