Matt Riedemann d004b0ecfa Fix NoneType error in _notify_volume_usage_detach 
If the driver.block_stats() method returns None, like the
libvirt driver will if the guest is gone during an evacuate,
we'll get a NoneType error trying to unpack the return value
from the driver. Instead, simply return as if the driver
raised NotImplementedError.

Since handling None is changing the contract on the virt
driver API, the docstring is updated to explain the acceptable
return values of the driver method.

Conflicts:
      nova/tests/unit/compute/test_compute_mgr.py

NOTE(mriedem): The conflict is due to not having the
test_get_scheduler_hints test from change
I49ffebcd129990f1835f404d98b51732a32171eb which was
added in Queens.

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:
