svm: queue sub: Add conditional timed wait
On reviece side svm queue only permits blocking and
non-blocking calls. This patch adds timed wait blocking
functionality which returns either on signal/event or
on given time out.
It also preserves the original behavior, so it will not
hurt client applications which are using svm queue.
