epoll: simplify ep_busy_loop by removing always 0 argument
Commit 00b27634bc471("epoll: replace gotos with a proper loop") refactored
ep_poll and always feeds ep_busy_loop with a time_out value of 0, nonblock
mode for ep_busy_loop has sunk since, IOW nonblock mode checking has been
taken over by ep_poll itself, codes snipped:
static int ep_poll(struct eventpoll *ep...
{
...
if (timed_out)
return 0;
eavail = ep_busy_loop(ep, timed_out);
...
}
Given this fact codes can be simplified a bit for ep_busy_loop.
