Subject: [PATCH] d80211: don't symlink empty default keys

This gets rid of annoying

wlan0: cannot create symlink to default key

in my syslog with latest rt2x00. The patch takes care that in case of
(key/old_key == NULL && set_tx_key) the existing default key symlink is
removed correctly. Moreover, it tests for key!=NULL before trying to register
a new default link.
