btrfs: switch extent_io_tree::private_data to btrfs_inode and rename

Browse source 
The extent_io_tree::private_data was meant to be a preparatory work for
the metadata inode rework but that never materialized. Now it's used
only for an inode so it's better to change the appropriate type and
rename it.
