mac80211: Use rhltable instead of rhashtable
mac80211 currently uses rhashtable with insecure_elasticity set to true. The latter is because of duplicate objects. What's more, mac80211 walks the rhashtable chains by hand which is broken as rhashtable may contain multiple tables due to resizing or rehashing. This patch fixes it by converting it to the newly added rhltable interface which is designed for use with duplicate objects. With rhltable a lookup returns a list of objects instead of a single one. This is then fed into the existing for_each_sta_info macro. This patch also deletes the sta_addr_hash function since rhashtable defaults to jhash.
