Shuhei Matsumoto 7baa78c86c bdev/nvme: Refactor _bdev_nvme_find_io_path() to cache non-optimized path for active/active
nbdev_ch->current_io_path is NULL at initialization.
bdev_nvme_find_io_path() calls _bdev_nvme_find_io_path() if
nbdev_ch->current_io_path is NULL. If there is no optimized path,
nbdev_ch->current_io_path is not filled. Hence, as long as there is no
optimized path, bdev_nvme_find_next_io_path() is never called.

However, bdev_nvme_find_next_io_path() fills nbdev_ch->current_io_path
even if the found path is non optimized.

This is a contradiction and a bug.

To fix this bug, as a preparation, refactor _bdev_nvme_find_io_path() to
cnosolidate bdev_nvme_find_next_io_path() and _bdev_nvme_find_io_path()
into a single function because  bdev_nvme_find_next_io_path() and
_bdev_nvme_find_io_path() were almost identical.
