btrfs: Remove fs_info argument from btrfs_uuid_tree_rem
This function always takes a transaction handle which contains a reference to the fs_info. Use that and remove the extra argument. Signed-off-by: Lu Fengqi <lufq.fnst@cn.fujitsu.com> Reviewed-by: Nikolay Borisov <nborisov@suse.com> [ rename the function ] Signed-off-by: David Sterba <dsterba@suse.com>
