dm: use signal_pending_state() in dm_wait_for_completion()

Use signal_pending_state() instead of open-coding it. This patch does
not change any functionality but makes it possible to pass TASK_KILLABLE
as the second argument of dm_wait_for_completion(). See also commit
16882c1e ("sched: fix TASK_WAKEKILL vs SIGKILL race").
