[PATCH v2] drivers: base: Remove statistics group if encryption group not created

["Ewan D. Milne" <emilne@redhat.com>]

If transport_add_class_device() gets an error from sysfs_create_group() when
creating the encryption group, it does not remove the statistics group in
the error path.  Adjust the error path to do this properly.

v2: Only remove statistics group if tcont->statistics is non-NULL
