[SCSI] scsi_dh_alua: Attach to UNAVAILABLE/OFFLINE AAS devices

2011-05-01T17:05:40Z

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.
