If an I/O fails during the write zeroes fallback to write on a split
I/O, the previous code would call spdk_bdev_io_complete() again on the
same I/O, causing infinite recursion.
Fix this by restoring the original user callback before completing the
I/O, as well as using _spdk_bdev_io_complete() rather than
spdk_bdev_io_complete() to avoid double-counting the statistics.
This also preserves the original bdev_io->status code set by the module,
rather than always setting it to SPDK_BDEV_IO_STATUS_FAILED.
