storage_controller: fix ReconcilerWaiter::get_status

[VladLazar]

Problem

SeqWait::would_wait_for returns Ok in the case when we would not wait for the sequence number and Err otherwise.
ReconcilerWaiter::get_status uses it the wrong way around. This can cause the storage controller to go into a busy loop
and make it look unavailable to the k8s controller.

Summary of changes

Use SeqWait::would_wait_for correctly.
