mac80211_hwsim module typically dumps a lot of details into the kernel message buffer. While it's probably okay in a dedicated VM, it's way too chatty in other setups. The kernel allows fine-tuning logging via the dynamic debugging facility. Let's enable all logging locations in the mac80211_hwsim module so that we don't loose debugging output when the kernel adopts the dynamic debug mechanism for the driver.
