eth: fbnic: update fbnic_poll return value

Browse Source 
In cases where the work done is less than the budget, `fbnic_poll` is
returning 0. This affects the tracing of `napi_poll`. Following is a
snippet of before and after result from `napi_poll` tracepoint. Instead,
returning the work done improves the manual tracing.
