net/nfp: fix return path in TSO processing

Browse Source 
When enable TSO, nfp_net_nfdk_tx_tso() fills segment information in Tx
descriptor. However, the return path for TSO is lost and the LSO related
fields of Tx descriptor is filled with zeros which prevents packets from
being sent.

This patch fixes the return path in TSO processing function to make sure
TSO works fine.
