enic: fix work done in tx napi_poll

With the commit d75b1ad ("net: less interrupt masking in NAPI") napi repoll is done only when work_done == budget. In tx napi poll we always return 0. So tx napi is not called again and we do not clean up the tx ring. Signed-off-by: Govindarajulu Varadarajan <[email protected]> Signed-off-by: David S. Miller <[email protected]>
