change_queue_depth allows changing per-target queue depth via sysfs. It also allows the SCSI midlayer to ramp down the number of concurrent inflight requests in response to a SCSI BUSY status response and allows the midlayer to ramp the count back up to the device maximum when the BUSY condition has resolved.

This implements the VIRTIO_SCSI_F_FC_HOST feature by reading the config fields and presenting them as sysfs fc_host attributes. The config change handler is added here because primary_active will toggle during migration.
