[PATCH 2/4] btrfs: Remove redundant bio_get/set from submit_dio_repair_bio

[Nikolay Borisov <nborisov@suse.com>]

The bio that is passsed is the newly created repair bio which already
has a reference count of 1, which is going to be consumed by the
endio routine on successful submission. On error the handler also
calls bio_put.
