btrfs: Remove EXTENT_WRITEBACK
This flag was introduced in a52d9a8033c4 ("Btrfs: Extent based page cache code.") and subsequently it's usage effectively was removed by 1edbb734b4e0 ("Btrfs: reduce CPU usage in the extent_state tree") and f2a97a9dbd86 ("btrfs: remove all unused functions"). Just remove it, no functional changes. Signed-off-by: Nikolay Borisov <nborisov@suse.com> Reviewed-by: David Sterba <dsterba@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>
