sched/wait: Make the signal_pending() checks consistent
There's two patterns to check signals in the __wait_event*() macros:
if (!signal_pending(current)) {
schedule();
continue;
}
ret = -ERESTARTSYS;
break;
And the more natural:
if (signal_pending(current)) {
ret = -ERESTARTSYS;
break;
}
schedule();
Change them all into the latter form.
