Log:
sbin/camcontrol/camcontrol.c
If an expander returns 0x00 (no device attached) in the ATTACHED DEVICE
field of the SMP DISCOVER response, ignore the value of ATTACHED SAS
ADDRESS, because it is invalid. Some expanders zero out the address
when the attached device is removed, but others do not. Section
9.4.3.10 of the SAS Protocol Layer 2 revision 04b does not require them
to do so.
