be2net: Handle out of buffer completions for lancer
If Lancer chip does not have posted RX buffers, it posts an RX completion entry with the same frag_index as the last valid completion. The Error bit is also set. In BE, a flush completion is indicated with a zero value for num_rcvd in the completion. Such completions don't carry any data and are not processed. This patch refactors code to handle both cases with the same code.
