net: thunderx: fix nicvf_set_rxfh()

This fixes a copypaste bug that was discovered by a static analysis
tool:

The patch 4863dea3fab0: "net: Adding support for Cavium ThunderX
network controller" from May 26, 2015, leads to the following static
checker warning:

        drivers/net/ethernet/cavium/thunder/nicvf_ethtool.c:517
nicvf_set_rxfh()
        warn: we tested 'hkey' before and it was 'false'

drivers/net/ethernet/cavium/thunder/nicvf_ethtool.c
   506          /* We do not allow change in unsupported parameters */
   507          if (hkey ||
                    ^^^^
We return here.

   508              (hfunc != ETH_RSS_HASH_NO_CHANGE && hfunc !=
ETH_RSS_HASH_TOP))
   509                  return -EOPNOTSUPP;
   510
   511          rss->enable = true;
   512          if (indir) {
   513                  for (idx = 0; idx < rss->rss_size; idx++)
   514                          rss->ind_tbl[idx] = indir[idx];
   515          }
   516
   517          if (hkey) {
                    ^^^^
So this is dead code.

   518                  memcpy(rss->key, hkey, RSS_HASH_KEY_SIZE *
sizeof(u64));
   519                  nicvf_set_rss_key(nic);
   520          }
   521
   522          nicvf_config_rss(nic);
   523          return 0;
   524  }
