Subject: [PATCH 5.4 051/111] dm verity: fix DM_VERITY_OPTS_MAX value

From: JeongHyeon Lee <jhs2.lee@...sung.com>

commit 160f99db943224e55906dd83880da1a704c6e6b9 upstream.

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.

Fixes: 843f38d382b1 ("dm verity: add 'check_at_most_once' option to only validate hashes once")
