mac80211: remove debug frame dumping 

You can just pull up a monitor interface to get much more
detailed information, or, when debugging a driver, insert
dump code into the driver (which usually you will have to
do anyway to dump the driver-specific information). Hence
this option is useless.

Selecting this option will cause the stack to
print a message for each frame that is handed
to the lowlevel driver for transmission. This
message includes all MAC addresses and the
frame control field.
If unsure, say N and insert the debugging code
you require into the driver you are debugging.
