[ upstream commit b8b5dc6b9596a07cbeed03192b41a4befb75acc6 ]
A terminated pthread should be joined or detached so that its associated
resources are released.
The "ark-delay-pg" thread is just used to delay some task but it is never
joined by the thread that created it.
The easiest solution is to detach the new thread.
Fixes: 727b3fe292bc ("net/ark: integrate PMD")
