btrfs: print-tree: print correct inline extent data size

We are advertising the ram_bytes of an inline extent as its data size, but
that is not true for compressed extents. The ram_bytes corresponds to the
uncompressed data size while the data size (compressed data) is given by
btrfs_file_extent_inline_item_len(). So fix this and print both values in
the same format as in btrfs-progs.
