mac80211: Fix NULL-pointer deference on ibss merge when not ready
dev_open will eventually call ieee80211_ibss_join which sets up the
skb used for beacons/probe-responses however it is possible to
receive beacons that attempt to merge before this occurs causing
a null pointer dereference. Check ssid_len as that is the last
thing set in ieee80211_ibss_join.
This occurs quite easily in the presence of adhoc nodes with hidden SSID's
revised previous patch to check further up based on irc feedback
