dm verity: fix DM_VERITY_OPTS_MAX value
Three optional parameters must be accepted at once in a DM verity table, e.g.: (verity_error_handling_mode) (ignore_zero_block) (check_at_most_once) Fix this to be possible by incrementing DM_VERITY_OPTS_MAX. Signed-off-by: JeongHyeon Lee <jhs2.lee@samsung.com> Fixes: 843f38d382b1 ("dm verity: add 'check_at_most_once' option to only validate hashes once") Cc: stable@vger.kernel.org Signed-off-by: Mike Snitzer <snitzer@redhat.com>
