The underlying mutex is recursive and judging from some logging, will have nested locks in some cases.

Setting the thread holder to 0 on every unlock without checking the number of lock calls results in incorrect asserts.

The line
lwip_core_lock_holder_thread_id = 0;

should only be executed when the last lock is released, either by keeping a counter to track locks/unlocks or (if possible) by getting that information from the mutex itself.
