I don't think such checks are necessary in scsi_try_to_abort_cmd(). scsi_remove_host() already waits until outstanding SCSI commands have finished. scsi_try_to_abort_cmd() only gets invoked if there are still one or more unfinished commands so scsi_try_to_abort_cmd() won't be invoked anymore after scsi_remove_host() has finished.
