I'm not sure if this is 100% correct.

pbuf_free() does not guarantee the pbuf-chain is fully freed,
it may also lower some reference counters, or free the chain partially.
Sometimes multiple calls to pbuf_free in a loop maybe required.
Setting the pointer to NULL without checking the return value
of pbuf_free might actually result in a leak.

Maybe the actual problem is in where an assumption/evaluation
is made on the pointer value where it is used.
