drbd: fix regression 'out of mem, failed to invoke fence-peer helper'
Since linux kernel 3.13, kthread_run() internally uses
wait_for_completion_killable(). We sometimes may use kthread_run()
while we still have a signal pending, which we used to kick our threads
out of potentially blocking network functions, causing kthread_run() to
mistake that as a new fatal signal and fail.
Fix: flush_signals() before kthread_run().
