Using static const generally increases object text and decreases data size.
It also generally decreases overall object size.

   text    data     bss     dec     hex filename

  41653    2205    9880   53738    d1ea drivers/net/wireless/rndis_wlan.o.new

Changed functions rndis_set_oid and set_bssid to take const *'s.
