btrfs-progs: Make btrfs_write_dirty_block_groups take only trans argument 

The root argument is used only to get a reference to the fs_info, this
can be achieved with the transaction handle being passed so use that.
This is in preparation for moving this function in the main transaction
commit routine. No functional changes.
