Fix debug print in GET_PREF_FREQ_LIST handler

Browse Source 
Do not use the buf argument to wpas_ctrl_iface_get_pref_freq_list() in
the debug print since it points to the response buffer ("OK\n" without
null termination). This was supposed to print the cmd argument instead.
The previous version ended up using uninitialized heap memory from the
response buffer.
