This condition was handled by submitting an IO for the mergeable portion then submitting a follow on IO for the remaining data after the previous IO completes. The remainder to be sent was tracked by manipulating the bio->bi_idx and bio->bi_sector. This patch splits the request as many times as necessary and submits the bios together. Since submitting the bio may cause it to be requeued on split, nvme_resubmit_bios had to be modified to remove the wait queue when the bio list is empty prior to submitting the bio since a split would have added the wait queue a second time, corrupting the wait queue head task list. There are a few other benefits from doing this: it fixes a potential issue with the previous handling of a non-mergeable bio as the requeuing method could would use an unlocked nvme_queue if the callback isn't invoked on the queue's associated cpu; it will be possible to retry a failed bio if desired at some later time since it does not manipulate the original bio; the bio integrity extensions require the bio to be in its original condition for the checks to work correctly if we implement the end-to-end data protection in the future.

Looking at the error path more closely reveals that we should return success from this function, even if no device namespaces are added. So once the queues are created and the device has responded to Identify, make sure that this function succeeds.

This fixes an integer overflow in the SCSI conversion layer, and it's slightly less typing than opencoding it.

For power efficiency reasons, I'd like this timer to happen together with other wakeups in the system. This patch makes the schedule_timeout() call in the kthread use round_jiffies_relative(), causing the wakeup to at least align with other "once per X seconds" events in the kernel.
