This patch fixes regression in iwlwifi IBSS rate scaling caused by patch:

mac80211: eliminate IBSS warning in rate_lowest_index()
An IBSS station might added on reception of a packet that doesn't
carry rate information (beacon, probe resp). In that case the rate
scaling was initialized only with single rate matching the received packet
rate with the hope that correct rate scale information will be updated
when beacon or probe for that station will arrive.
iwl-agn-rs copied supported rates on initialization and was never updated
again.
