Shuhei Matsumoto 772e6db413 bdev/nvme: Save io_path into nvme_bdev_io to reuse it while processing I/O 
Save the io_path to which the current I/O is submitted into struct
nvme_bdev_io to know which io_path caused I/O error, or to reuse it
to avoid repeated traversal.

Besides, add a simple helper function nvme_io_path_is_available() to
check if the io_path can be reused.
