zbd: prevent experimental verify with zonemode=zbd

When the experimental_verify option is specified, fio does not record
normal I/O metadata to create verify read unit. Instead, fio resets file
status after normal I/O and before verify start, then replay I/Os to
regenerate write unit and adjust it to verify read. This I/O replay does
not work for zonemode=zbd since zone status needs to be restored at
verify start to the status before the normal I/O. However, such status
restore moves write pointers and erases data pattern for verify.

Check that the options experimental_verify and zonemode=zbd are not
specified together and error out in case they are both specified. Also
remove the helper function zbd_replay_write_order() which is called from
zbd_adjust_block(). This function adjusts verify read unit to meet zone
write restrictions for experimental verify, but such adjustment does not
work because zone status is not restored before verify start.
