staging: wlan-ng: Remove unused struct wlan_ie_supp_rates references

Pointer reference to struct wlan_ie_supp_rates is added as a member
variable to 7 different 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.
