[PATCH 3.11 043/144] iscsi-target: Fix iscsit_get_tpg_from_np tpg_state bug

From: Luis Henriques
Date: Tue Apr 01 2014 - 08:08:58 EST -stable review patch. If anyone has any objections, please let me know.


From: Nicholas Bellinger <nab@xxxxxxxxxxxxxxx>

commit a2a99cea5ec7c1e47825559f0e75a4efbcf8aee3 upstream.

This patch fixes a bug in iscsit_get_tpg_from_np() where the
tpg->tpg_state sanity check was looking for TPG_STATE_FREE,
instead of != TPG_STATE_ACTIVE.

The latter is expected during a normal TPG shutdown once the
tpg_state goes into TPG_STATE_INACTIVE in order to reject any
new incoming login attempts.
