drivers/net/qlge: fix sparse warnings: make symbols static

Fix this sparse warnings:

  drivers/net/qlge/qlge_ethtool.c:100:6: warning: symbol 'ql_update_stats' was not declared. Should it be static?
  drivers/net/qlge/qlge_mpi.c:22:5: warning: symbol 'ql_get_mb_sts' was not declared. Should it be static?
