Subject: [PATCH net-next 4/4] qed: Enlrage the drain timeout

In the scenario where slowpath configuration isn't passing due to
various pause configurations affecting the chip, the theoretical time
required in worst-case-scenario to empty hw fifos sufficiently to
guarantee that slowpath configuration would flow is currently
insufficient.

This increases such a drain request to the theoretical maximum.
