Subject: common/TracepointProvider: add assert if dlopen error.
X-Git-Tag: v12.0.1~353^2

common/TracepointProvider: add assert if dlopen error.

Because some reasons, if dlopen error the ceph-osd still work. But we
don't see related tracepoint by 'lttng list -u'. So add this assert to
make easily find the problem.
