 Description    

AliSQLBackup depends on tokudb_checkpoint_lock to implement hot backup, but
 
invoking ft_close() to a FT file during backup will break the consistency
 
between this FT and the others in the final backup directory, even when
 
checkpoint lock is held, becasue the header of FT is updated by ft_close().
 
 
 
This patch checks whether we are in backup before closing FT, if in backup,
 
don't close FT.
