Btrfs: Update on disk i_size only after pending ordered extents are done
This changes the ordered data code to update i_size after the extent is on disk. An on disk i_size is maintained in the in-memory btrfs inode structures, and this is updated as extents finish. Signed-off-by: Chris Mason <chris.mason@oracle.com>
