btrfs: Remove redundant pair of bio_get/set in __btrfs_submit_dio_bio 



The bio is not referenced after it has been submitted and the endio is
going to consume the sole reference on successful submission. On error,
the callers of __btrfs_submit_dio_bio do invoke bio_put so we don't
leak it either.
