[stgt] Login problem when use iser

[charles zhuang]

Hi,
I am trying to use iser between my initiator and target but encountered
a login problem.
Both initiator and target use centos 5.3, ofed 1.4, mellanox nic.
Here's the output from initiator side, which I believe it's a problem of
the initiator.  Any tips will be greatly appreciated.
