[SCSI] sas: fix removal of devices behind expanders
We need to iterate over all children when removing and expander, else stale objects will be around after host removal. This fixes the oops Eric Moore saw when removing and reloading mptsas. Also don't try the scsi_remove_target call unless operating on an end device. The current unconditional call is harmless but confusing.
