01ad35e6 - CANN: Define `cann_graph_update_required` before macro (#17434)

CANN: Define `cann_graph_update_required` before macro (#17434) **Description of the problem** `cann_graph_update_required` is redundantly defined and initialized as `false` inside two mutually exclusive macro branches. **Proposed solution** Define it right before the macro so that it could serve both branches.
