nvme: mark internal passthru request RQF_QUIET

Most of the internal passthru commands use __nvme_submit_sync_cmd()
interface. There are few places we open code the request submission :-

1. nvme_keep_alive_work(struct work_struct *work)
2. nvme_timeout(struct request *req, bool reserved)
3. nvme_delete_queue(struct nvme_queue *nvmeq, u8 opcode)

Mark the internal passthru request quiet so that we can skip the verbose
error message from nvme_log_error() in nvme_end_req() completion path,
this will be consistent with what we have in __nvme_submit_sync_cmd().
