When built with RAID support, we need to determine if this table
makes use of the raid feature. If yes, we need to remove all raid
chunks. This is done with my_raid_delete(). Unfortunately it is
necessary to open the table just to check this. We use
'open_for_repair' to be able to open even a crashed table. If even
this open fails, we assume no raid configuration for this table
and try to remove the normal data file only. This may however
leave the raid chunks behind.
