3.0-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Nicholas Bellinger <n...@linux-iscsi.org>

commit 30f359a6f9da65a66de8cadf959f0f4a0d498bba upstream.

This patch fixes a bug where a handful of informational / control CDBs
that should be allowed during ALUA access state Standby/Offline/Transition
where incorrectly returning CHECK_CONDITION + ASCQ_04H_ALUA_TG_PT_*.

This includes INQUIRY + REPORT_LUNS, which would end up preventing LUN
registration when LUN scanning occured during these ALUA access states.
