tcp_abort currently shouldn't be used from one of the callback 
functions: http://savannah.nongnu.org/bugs/?27871

Can you try replacing that with tcp_close(); and return ERR_OK;? In any 
case, calling tcp_recved() won't hurt, too. (Although before tcp_abort, 
it shouldn't be necessary - once the above bug is fixed.)
