dm thin: fix bug where bio that overwrites thin block ignores FUA (2019-02-14 19:02:29 -0500)

Please pull, thanks.

----------------------------------------------------------------
- Fix bug in DM crypt's sizing of its block integrity tag space, resulting in less memory use when DM crypt layers on DM integrity.

- Fix a long-standing DM thinp crash consistency bug that was due to improper handling of FUA. This issue is specific to writes that fill an entire thinp block which needs to be allocated.
