Btrfs updates for 4.18, part 2

Hi,

a handful of minor updates that would fit the 1st pull but were in next at that time or arrived last week and there's no reason to delay them for later rc.

Please pull thanks.

- error handling fixup for one of the new ioctls from 1st pull
- fix for device-replace that incorrectly uses inode pages and can mess up compressed extents in some cases
- fiemap fix for reporting incorrect number of extents
- vm_fault_t type conversion

----------------------------------------------------------------
