Fix: Remove LPOLLNVAL from consumer metadata revents

Without epoll(7), this value does not exist in the compat layer. For
now, this poll error is set within the LPOLLHUP in the poll(2) compat
header and POLLNVAL of epoll is set to POLLHUP so we basically don't
need it at all if we simply use the LPOLLHUP code.
