An optional field was added in NVMe 1.3 to indicate the optimal I/O
boundary that should not be crossed for best performance. This is
equivalent to the existing Intel-specific stripe size quirk.
Add support for the new NOIOB field and move the current quirk-based
code so it is updated in nvme_ns_identify_update().

There is one scenario, when one large read IO is splitted into several
subtasks 1 - N, and the subtask N return successful, it will be stored
in the subtask_list of primary task, but the other tasks could return
error, then when we try to return the subtask N, it will failed, this patch
will make sure the large read IO command return correctly if any of the
subtasks failed.
