mac80211: (really) fix rates setup on IBSS mergemaster-2010-03-16
when an IBSS merge happened, the supported rates for the newly added station were left empty, causing the rate control module to be initialized with only the basic rates. the section of the ibss code which deals with updating supported rates for an already existing station failed to inform the rate control module about the new rates. as both minstrel and pid don't have an update function i just use the init function. also remove unnecessary (unsigned long long) casts and edit debug message.
