[PATCH net-next] igc: Make function igc_write_rss_indir_tbl() static

[Wei Yongjun]

Fixes the following sparse warning:

drivers/net/ethernet/intel/igc/igc_ethtool.c:646:6: warning:
 symbol 'igc_write_rss_indir_tbl' was not declared. Should it be static?

Fixes: 8c5ad0dae93c ("igc: Add ethtool support")
