The commit ec29d0ac29be ("scsi: iscsi: Fix conn use after free during
resets") move member ehwait from conn to session, but left init ehwait
in iscsi_conn_setup().
Although a session can only have 1 conn currently, it is better to
do init ehwait in iscsi_session_setup() to prevent reinit by mistake,
also in case we can handle multiple conns in the future.
