[PATCH] nl80211: remove unnecessary cfg80211_ssid pointer in nl80211_trigger_scan

[Luciano Coelho <coelho@ti.com>]

The struct cfg80211_ssid *ssid variable was only used to figure out
the size of the struct when allocating memory.  This is not necessary,
because sizeof(*request->ssids) can be used instead.
