[PATCH 8/9] WNM: Do not store coloc_intf_elems

[benjamin at sipsolutions.net]

From: Benjamin Berg <benjamin.berg at intel.com>

The elements are (currently) not used except for sending an immediate
response similar to COLOC_INTF_REPORT with the main difference being
that the dialog token is included.

Do not store the elements. It easy enough to re-add this should the
implementation improve. And this fixes the fact that the variable is
cleared at odd times as wnm_deallocate_memory is used specifically to
clear the neighbor report list of a BTM request.
