mac80211: fix SSID copy on IBSS JOIN

commit badecb001a310408d3473b1fc2ed5aefd0bc92a9 upstream.

The 'ssid' field of the cfg80211_ibss_params is a u8 pointer and
its length is likely to be less than IEEE80211_MAX_SSID_LEN most
of the time.

This patch fixes the ssid copy in ieee80211_ibss_join() by using
the SSID length to prevent it from reading beyond the string.
