mac80211: Fix rate scale initialization in IBSS

Browse Source 
This patch address some IBSS rate issues introduced or not covered
by "mac80211: eliminate IBSS warning in rate_lowest_index()" and
"cfg80211 API for channels/bitrates, mac80211 and driver conversion".

This patch:
1. Moves addition of IBSS station from
prepare_for_handlers to ieee80211_rx_bss_info when triggered from beacon
eliminating bogus supported rates.
2. Initialize properly supported rates also in IBSS merging
3. Ensure that mandatory rates are always added into supported
rates. This is needed in case when station addition is triggered from
non beacon/probe packet. Some management frames need to be sent
4. Remove initialization of supported rates from self rates. This path
was dead code after 6bc37c06bc4 and in general incorrect.
