Don't drop a reference to the TOE PCB in undo_offload_socket().

Browse Source 
undo_offload_socket() is only called by t4_connect() during a connection
setup failure, but t4_connect() still owns the TOE PCB and frees ita
after undo_offload_socket() returns.  Release a reference in
undo_offload_socket() resulted in a double-free which panicked when
t4_connect() performed the second free.  The reference release was
added to undo_offload_socket() incorrectly in r299210.
