Shuhei Matsumoto ef409194a1 bdev/nvme: Retry I/O a second later if any I/O path may become available ... If ANA state is inaccessible or qpair is disconnected, I/O cannot be submitted. But if qpair is connected, ANA state may become accessible, or if qpair is disconnected, it may become connected via resetting. Hence even if find_io_path() returned NULL, queue I/O and retry it one second later if qpair is connected or ctrlr is resetting. Sort retried I/Os by expiration values in ticks, and activate a timed poller per nvme_bdev_channel only if there is any retried I/O. So the poller function bdev_nvme_retry_ios() always returns BUSY because if the poller runs earlier than the closest retried I/O or runs when there is no retried I/O, it is more like a bug of the framework.
