Btrfs: remove no longer used member num_dirty_bgs from transaction
The member num_dirty_bgs of struct btrfs_transaction is not used anymore, it is set and incremented but nothing reads its value anymore. Its last read use was removed by commit 64403612b73a94 ("btrfs: rework btrfs_check_space_for_delayed_refs"). So just remove that member.
