[SCSI] libsas: Don't issue commands to devices that have been hot-removed
sd will get hung up issuing commands to flush write cache if a SAS
device behind the expander is unplugged without warning. Change libsas
to reject commands to domain devices that have already gone away.
[maciej.trela@intel.com: removed setting ->gone in sas_deform_port() to
permit sync cache commands at module removal]
