[PATCH] libosmocore[master]: Catch repeated calls to osmo_init_logging()

[Harald Welte]

Review at  https://gerrit.osmocom.org/4562

Catch repeated calls to osmo_init_logging()

If an application calls osmo_init_logging() multiple times, let's
bail out in a safe way without corrupting the state + returning an
error.
