  Free any datastores attached to dummy channels.

  Revision 370205 added the use of a datastore attached to a dummy channel to
  resolve a memory leak, but ast_dummy_channel_destructor() in this branch did
  not free datastores, resulting in a continued (but slightly smaller) memory
  leak. This patch backports the change to free said datastores from the Asterisk
  trunk.
