ieee80211: Stop net_ratelimit/IEEE80211_DEBUG_DROP log pollution
if (net_ratelimit()) IEEE80211_DEBUG_DROP(...) can pollute the logs with messages like: printk: 1 messages suppressed. printk: 2 messages suppressed. printk: 7 messages suppressed. if debugging information is disabled. These messages are printed by net_ratelimit(). Add a wrapper to net_ratelimit() that takes into account the log level, so that net_ratelimit() is called only when we really want to print something.
