net: hns3: fix a bug about hns3_clean_tx_ring
The return value of hns3_clean_tx_ring means tx ring clean result.
Return true means clean complete and there is no more pakcet need
clean. Retrun false means there is packets need clean and napi need
poll again. The last return of hns3_clean_tx_ring is
"return !!budget" as budget will decrease when clean a buffer.
If there is no valid BD in TX ring, return 0 for hns3_clean_tx_ring
will cause napi poll again and never complete the napi poll. This
patch fixes the bug.
