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

From: Nicholas Bellinger <nab@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.
