The libertas driver copies the SSID buffer back to the wireless core and
appends a trailing NULL character for termination. This is
a) unnecessary because the buffer is allocated with kzalloc and is hence
already NULLed when this function is called, and
b) for priv->curbssparams.ssid_len == 32, it writes back one byte too
much which causes memory corruptions.
Fix this by removing the extra write.
