reiserfs: workaround for dead loop in finish_unfinished
There is possible dead loop in finish_unfinished function.
In most situation, the call chain iput -> ... -> reiserfs_delete_inode ->
remove_save_link will success. But for some reason such as data
corruption, reiserfs_delete_inode fails on reiserfs_do_truncate ->
search_for_position_by_key.
Then remove_save_link won't be called. We always get the same
"save_link_key" in the while loop in finish_unfinished function. The
following patch adds a check for the possible dead loop and just remove
save link when deap loop.
