vcl: postpone unhandled ctrl events if needed

Unhandled control events, i.e., events delivered outside of epoll/select loops, that need to be propagated to apps should be postponed such that epoll and select can later deliver them. Type: fix Signed-off-by: Florin Coras <fcoras@cisco.com> Change-Id: I3d05e154382631a16a19e71494c2d92c35dacb70
