wlan: Use Metainfo to fill privacy bit in the frame control

For WAI frames, gUcIsWai is used to decide the privacy bit in the
frame control in case tlState is WLANTL_STA_AUTHENTICATED.
gUcIsWai can be 0 for WAI frames in some case, and thus privacy
bit of WAI frame is set. So instead use Metainfo->ucIsWai, which
is filled for all WAI frames.
