Sergei Golubchik a50e6c9eb1 MDEV-17153 server crash on repair table ... use_frm ...

data_file_length == 0 in mi_repair() is normal for REPAIR ... USE_FRM.
But in-file links (for blocks and deleted chain) must be compared with
the real file length to avoid spurious "link points outside datafile"
warnings and arbitrary block skipping.
