From: Mike Christie <michaelc@xxxxxxxxxxx> alua_activate only sends a STPG if only explicit is suppored. As a result, for EMC targets that support both we end up doing a implicit failover when X commands are finally sent to the other SP. This patch does a AND on the h->tpgs, so we do a explicit failover right away.
