staging: wlan-ng: Remove unused struct wlan_ie_ibss_parms references

Pointer reference to struct wlan_ie_ibss_parms is added as a member variable to 2 structures; However, these references are never used. Remove such unused struct references. The cleanup also renders the struct useless; so remove it as well. Issue identified as part of coccicheck based code analysis.
