The SCSI ALUA handler currently fails to attach to devices reporting an UNAVAILABLE/OFFLINE AAS. But given that an UNAVAILABLE/OFFLINE AAS can transition to other states like ACTIVE/OPTIMIZED, ACTIVE/NON-OPTIMIZED, etc. as per SPC4, this ALUA handler behavior should be rectified so as to attach to devices which also report an UNAVAILABLE/OFFLINE AAS. The below patch enables the same.
