[PATCH] Fix DRBD regression

Hi Jens, In 3.13 the commit 786235eeb 'kthread: make kthread_create() killable' broke DRBD's fence peer mechanism in a subtle way. Since only a part of our user base has fencing properly configured this regression was unnoticed until now. Please consider to submit this for 3.16-rc5. Thanks, Phil
