[lwip-users] pbuf ASSERT triggering

[Karl Jeacle]

Small problem:

When data is passed to a receiving application, "inseg.p" is set to NULL
before being passed to pbuf_free() - this is triggering an LWIP_ASSERT.

tcp_in.c:1004, inseg.p = NULL
tcp_in.c:354,  pbuf_free(inseg.p)
pbuf.c:553,    LWIP_ASSERT("p != NULL", p != NULL);

Presumably inseg.p should be checked to see if it's NULL before calling
pbuf_free() at tcp_in:354.

The LWIP_ASSERT first appeared in v1.65 of pbuf.c (end April).
