mac80211_hwsim: Fix memory leak in hwsim_new_radio_nl()

hwsim_new_radio_nl() now copies the name attribute in order to add a
null-terminator.  mac80211_hwsim_new_radio() (indirectly) copies it
again into the net_device structure, so the first copy is not used or
freed later.  Free the first copy before returning.
