Subject: [PATCH] nvme: Initialize ANA state to optimized if ANA reporting is
 not supported

Initialize ANA state of each namespace to optimized regardless of
whether ANA is supported or not. This will simplify the code to get
the optimal I/O path because we do not have to care if the namespace
supports ANA.
