scsi: core: Clear flags for scsi_cmnd that did not complete

Commands that have not been completed with scsi_done() do not clear the
SCMD_INITIALIZED flag and therefore will not be properly reinitialized.
Thus, the next time the scsi_cmnd structure is used, the command may
fail in scsi_cmd_runtime_exceeded() due to the old jiffies_at_alloc
value:

  kernel: sd 16:0:1:84: [sdts] tag#405 timing out command, waited 720s
  kernel: sd 16:0:1:84: [sdts] tag#405 FAILED Result: hostbyte=DID_OK driverbyte=DRIVER_OK cmd_age=66636s

Clear flags for commands that have not been completed by SCSI.

Fixes: 4abafdc4 ("block: remove the initialize_rq_fn blk_mq_ops method")
