This update will allow us to use spdk_nvme_detach_async() and
spdk_nvme_detach_poll_async() easier to aggregate multiple detachments.
Previously, we could do:
spdk_nvme_detach_async()
spdk_nvme_detach_async()
spdk_nvme_detach_async()
and then started doing spdk_nvme_detach_poll_async().
Hence aggregating multiple detachments is already supported.
After this patch, the following sequence is possible:
spdk_nvme_detach_async() = 0
spdk_nvme_detach_async() = 0
spdk_nvme_detach_async() = 0
spdk_nvme_detach_poll_async() = -EAGAIN
spdk_nvme_detach_async() = 0
spdk_nvme_detach_async() = 0
spdk_nvme_detach_poll_async() = -EAGAIN
spdk_nvme_detach_poll_async() = -EAGAIN
spdk_nvme_detach_poll_async() = -EAGAIN
spdk_nvme_detach_poll_async() = 0
The actual changes is to remove the variable polling_started from
struct spdk_nvme_detach_ctx because it is not necessary anymore.
Clarify this change via updating the header file and CHANGELOG.
Verify this change by unit test.
