Subject: [PATCH] [SCSI] scsi_transport_sas: fix the lifetime of sas bsg
 objects

scsi_transport_sas calls blk_cleanup_queue too early for bsg
queues. If a user holds a sas_host, end_device, or expander device
open, remove the device, then send a request to it, we get a kernel
crash. We need to call blk_cleanup_queue in the release callback as we
do with scsi devices.

This patch moves blk_cleanup_queue to sas_expander_release and
sas_end_device_release from sas_bsg_remove. sas_host can't use the
release callback in struct device so use bsg's release callback.
