Subject: [PATCH v2 4/7] 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.
