Btrfs fixes for 4.16-rc6

Hi,

there's an important revert in this pull request that needs to go to stable as it causes a corruption on big endian machines. The other fix is for FIEMAP incorrectly reporting shared extents before a sync and one fix for a crash in raid56.

So far we got only one report about the BE corruption, the stable kernels were out for like a week, so hopefully the scope of the damage is low.

Please pull, thanks.
