ipw2x00: remove unused ->ibss_dfs pointer
The ->ibss_dfs pointer is always allocated with a user controlled
length. This caused a static checker warning because what if the length
was zero? In that case, any dereference of ->ibss_dfs would lead to an
Oops.
It turns out that this isn't a problem because the ->ibss_dfs pointer is
never used. This patch deletes it along with all the related code. In
particular the entire libipw_network_reset() function can be removed.
