MDEV-31803 InnoDB aborts during recovery when immediate_scrub_data_uncompressed is enabled

Browse source 
Problem:
========
 - InnoDB scans the complete redo log to ensure that there is
no corruption and to find the end of the log. During this scan,
InnoDB saves all the freed ranges, but it doesn't save
recovered size. Later, InnoDB recovery applies partial
redo logs and IO thread tries to flush the all freed
ranges which was noted during previous complete scan of redo logs.

Fix:
====
 InnoDB should store the freed pages only when InnoDB stores
 the redo log records.
