Description:
The attrcrypt module maintains the inst_attrcrypt_state_private
field in the instance structure (ldbm_instance) to store the private
keys.  The area and the space for the private keys are allocated in
attrcrypt_init which is called from dblayer_instance_start.
A backend instance could be closed and restarted multiple times
(for instance, in the bulk_import, which is used by the replica
initialization), but the area had no chance to be freed.
This patch is adding the clean-up code.
