Subject: [PATCH 3.12 096/170] mac80211: fix IBSS join by initializing last_scan_completed

From: Krzysztof Hałasa <khalasa@...p.pl>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit c7d37a66e345df2fdf1aa7b2c9a6d3d53846ca5b upstream.

Without this fix, freshly rebooted Linux creates a new IBSS
instead of joining an existing one. Only when jiffies counter
overflows after 5 minutes the IBSS can be successfully joined.
