Subject: [PATCH v2 3/7] staging: wlan-ng: Remove unused struct wlan_ie_tim
 references

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