during mariabackup --prepare
Reason:
======
During --prepare of partial backup, if InnoDB encounters the redo log
for the excluded tablespace then InnoDB stores the space id in dirty
tablespace list during recovery, anticipates that it may encounter
FILE_* redo log records in the future. Even though we encounter FILE_*
record for the partial excluded tablespace then we fail to replace the
name in dirty tablespace list. This lead to missing of
FILE_* redo log records error.
Solution:
========
fil_name_process(): Rename the file name from "" to name encountered
during FILE_* records
