btrfs: remove no longer used trans_list member of struct btrfs_ordered_extent
The 'trans_list' member of an ordered extent was used to keep track of the ordered extents for which a transaction commit had to wait. These were ordered extents that were started and logged by an fsync. However we don't do that anymore and before we stopped doing it we changed the approach to wait for the ordered extents in commit 161c3549b45aee ("Btrfs: change how we wait for pending ordered extents"), which stopped using that list and therefore the 'trans_list' member is not used anymore since that commit. So just remove it since it's doing nothing and making each ordered extent structure waste memory (2 pointers).
