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.
