zbd: remove unnecessary verify_backlog check in zbd_file_reset()

The commit c5c8b92be5a2 ("zbd: fix zone reset condition for verify")
improved zbd_file_reset() to not reset zones when data to verify is
left. To check the left verify data, it tried to do the same as
check_get_verify() including the check for the modulo operation
"td->io_hist_len % td->o.verify_backlog". This check is required in
check_get_verify() to know when to do the verify backlog operation.
However, this check is not required in zbd_file_reset() since zone reset
is not related to the verify backlog timing. The unnecessary check for
"td->io_hist_len % td->o.verify_backlog" allows to reset zones even when
td->io_hist_len is non-zero and the data to verify is left. It erases
the data to verify and causes verify errors. Fix this by removing the
unnecessary check.
