[S] Change in osmo-uecups[master]: gtp_endpoint: Avoid deadlocks logging while thread is cancelled

Attention is currently required from: fixeria, laforge, osmith, pespin. Hello Jenkins Builder, fixeria, osmith, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/osmo-uecups/+/40788?usp=email to look at the new patch set (#4). The following approvals got outdated and were removed: Code-Review+1 by fixeria, Code-Review+1 by osmith Change subject: gtp_endpoint: Avoid deadlocks logging while thread is cancelled ...................................................................... gtp_endpoint: Avoid deadlocks logging while thread is cancelled We cannot guarantee that LOGP will not end up calling a syscall which can be a cancellation point. Since the syscall will be probably called while having the logging mutex locked, an eventual cancellation of the thread would leave the logging mutex locked forever, hence making all other threads deadlock as soon as they try to write anything to the log. Similar to what's already done in tun_device_thread().
