eth: fbnic: update fbnic_poll return value

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.

Before:
@[10]: 1
...
@[64]: 208175
@[0]: 2128008

After:
@[56]: 86
@[48]: 222
...
@[5]: 1885756
@[6]: 1933841
