need patch to inst->session_tail clear ?

[blue_11j at yahoo.co.jp]

Hi,
  I'm *sorry* that I am not good at English
  because I'm Japanese....

I think that it is need following patch for eaplist_find()
in rlm_eap/mem.c, FreeRADIUS 1.1.7.
if no patch, when session_head == NULL and session_tail != NULL,
add handler to TAIL in next eaplist_add().
How do you think about it?
