Richael Zhuang 61b8122dc5 bdev_nvme: added io_outstanding in nvme_io_path
Added io_outstanding in struct nvme_io_path to record outstanding
I/O number in each path, which will be used by multipath to select
I/O path.

io_outstanding gets updated for I/O sent to a namespace and not get
updated if sent to a controller.
For FLUSH case, it calls bdev_nvme_io_complete() directly and
io_outstanding is not updated for this case.
spdk_bdev_io_get_buf() is executed in the generic bdev layer.
Hence, we do not update io_outstanding for spdk_bdev_io_get_buf().
