[0/2] dm vdo recovery: improve old journal format handling

Message

Some older out-of-tree versions of vdo use a format for recovery
journal entries that cannot be processed by the current recovery
code. For vdo volumes created with these older versions, reduce
the likelihood of entering read-only mode.

This will ease the transition of older volumes to the in-kernel
dm-vdo target.

  dm vdo: abort loading dirty VDO with the old recovery journal format
  dm vdo: force read-only mode for a corrupt recovery journal
