Remove deprecated interruptible_sleep_on_timeout() function calls
and replace with direct wait-queue usage or wait_event() as appropriate. The
former replacements result in the same code. The latter change the tasks from
interruptible to uninterruptible, as signals were not being checked in the
current code. The corresponding wake_up() calls were fixed as well. This patch
will result in some slightly different debug output (for instance, one output
instead of one per iteration). Patch is compile-tested.
