Subject: [PATCH] Skip to remove resource provider if compute node not found

As user may change compute service's hostname or compute driver,
this service may have no hypervisor node and the service of compute_node
value may be None. For this case, We just ignore this and let the delete
workflow go on.

Closes-Bug: 1809693
