[SCSI] libiscsi: avoid unnecessary multiple NULL assignments
In iscsi_free_task, NULL is assigned to task->sc twice: before and after kfifo_in invocatoin. Allocating and freeing iscsi_task are guarded with session->lock, so multiple NULL assignments cause no trouble. But people reading the source code may be confused. The second NULL assignment comes from commit: 3e5c28ad0391389959ccae81c938c7533efb3490 It seems that the line after kfifo_in invocation was introduced accidentally.
