Delete volume transfer in volume_destroy function

Delete volume transfer in volume_destroy function

Doing volume force delete operation on volume-A will change volume-A's
status to 'deleted', so all related data about volume-A should be deleted.
Now current version's volume_destroy function doesn't delete related data
of volume transfer. If there is volume transfer about volume-A, first do
force delete operation on volume A, and thus the volume-A's transfer data
would be residual. So remove the related data of volume transfer in
volume_destroy function.
