In prealloc_file_extent_cluster(), btrfs_check_data_free_space() uses
wrong file offset for reloc_inode, it uses cluster->start and cluster->end,
which indeed are extent's bytenr. The correct value should be
cluster->[start|end] minus block group's start bytenr.
start bytenr cluster->start
| | extent | extent | ...| extent |
|----------------------------------------------------------------|
| block group reloc_inode |
