Subject: [PATCH net 2/2] bnx2x: fix napi poll return value for repoll

With the commit d75b1ade567ffab ("net: less interrupt masking in NAPI") napi repoll
is done only when work_done == budget. When in busy_poll is we return 0 in
napi_poll. We should return budget. Also do not return workdone > budget.
