volumes are not deleted in teardown

[Dmitry Russkikh]

In tempest/tests/test_volumes_list.py

there is a typo in the deletion method declaration.

Expected:

 28 @classmethod
 29 def tearDownClass(cls):
 30 #Delete the created Volumes
 31 for i in range(3):
 32 resp, _ = cls.client.delete_volume(cls.volume_id_list[i])

Actual:
 28 def teardown(cls):
 29 #Delete the created Volumes
 30 for i in range(3):
 31 resp, _ = cls.client.delete_volume(cls.volume_id_list[i])
