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.
