[SCSI] libsas: fix false positive 'device attached' conditions
Normalize phy->attached_sas_addr to return a zero-address in the case
when device-type == NO_DEVICE or the linkrate is invalid to handle
expanders that put non-zero sas addresses in the discovery response:
sas: ex 5001b4da000f903f phy02:U:0 attached: 0100000000000000 (no device)
sas: ex 5001b4da000f903f phy01:U:0 attached: 0100000000000000 (no device)
sas: ex 5001b4da000f903f phy03:U:0 attached: 0100000000000000 (no device)
sas: ex 5001b4da000f903f phy00:U:0 attached: 0100000000000000 (no device)
