[PATCH for device-mapper/for-next] dm integrity: follow ReST formatting

[Lukas Bulwahn]

Commit 61b8b2a834bf ("dm integrity: introduce the "fix_hmac" argument")
adds some new part to dm-integrity.rst, but this causes make htmldocs warn:

  dm-integrity.rst:192: WARNING: Unexpected indentation.
  dm-integrity.rst:193: WARNING: Block quote ends without a blank line; \
    unexpected unindent.

Make dm-integrity.rst follow ReST formatting.

 fix_hmac
 	Improve security of internal_hash and journal_mac:
+
 	- the section number is mixed to the mac, so that an attacker can't
 	  copy sectors from one journal section to another journal section
 	- the superblock is protected by journal_mac
