dm integrity: fix recalculation when moving from journal mode to bitmap mode

If we resume a device in bitmap mode and the on-disk format is in journal
mode, we must recalculate anything above ic->sb->recalc_sector. Otherwise,
there would be non-recalculated blocks which would cause I/O errors.

Fixes: 468dfca38b1a ("dm integrity: add a bitmap mode")
