[PATCH] multipath-tools: align ALUA state strings with kernel scsi_sysfs

Update ALUA asymmetric access state descriptions in the prioritizer to
match the shorter names defined in the SCSI kernel subsystem:

   $ grep  "{ SCSI_ACCESS_STATE_"  linux/drivers/scsi/scsi_sysfs.c 
        { SCSI_ACCESS_STATE_OPTIMAL, "active/optimized" },
        { SCSI_ACCESS_STATE_ACTIVE, "active/non-optimized" },
        { SCSI_ACCESS_STATE_STANDBY, "standby" },
        { SCSI_ACCESS_STATE_UNAVAILABLE, "unavailable" },
        { SCSI_ACCESS_STATE_LBA, "lba-dependent" },
        { SCSI_ACCESS_STATE_OFFLINE, "offline" },
        { SCSI_ACCESS_STATE_TRANSITIONING, "transitioning" },

This unifies diagnostic strings across the stack and replaces the misleading
"ARRAY BUG: invalid TPGs state!" message with the standard SPC "reserved"
designation. These codes are explicitly reserved for future standard
definitions rather than being treated as malformed states.
