btrfs: Remove redundant pair of bio_get/set in __btrfs_submit_dio_bio

Browse Source 
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.
