[RESEND PATCH] tests: enable dynamic debugging for mac80211_hwsim

[Lubomir Rintel]

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.

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 kenel adpots the dynamic debug mechanism for
the driver.
