SUNRPC: allow svc_recv to break out of 500ms sleep when alloc_page fails
svc_recv() calls alloc_page(), and if it fails it does a 500ms uninterruptible sleep and then reattempts. There doesn't seem to be any real reason for this to be uninterruptible, so change it to an interruptible sleep. Also check for kthread_stop() and signalled() after setting the task state to avoid races that might lead to sleeping after kthread_stop() wakes up the task. I've done some very basic smoke testing with this, but obviously it's hard to test the actual changes since this all depends on an alloc_page() call failing.
