mac80211: ensure no limits on station rhashtable
By default, the rhashtable logic will fail to insert
objects if the key-chains are too long and un-balanced.
In the degenerate case where mac80211 is creating many
virtual interfaces connected to the same peer(s), this
case can happen.
St insecure_elasticity to true to allow chains to grow
as long as needed.
