mac80211: minstrel_ht: sample_table can be __read_mostly
The sample table is initialized only once at module start, so is really __read_mostly. Additionally, the code to init it can be marked __init since it will never be needed again, it is likely automatically inlined into the __init function already by the compiler, so this doesn't really make a difference.
