block: fix an error code in add_partition()
We don't set an error code on this path. It means that we return NULL instead of an error pointer and the caller does a NULL dereference. Fixes: 6d1d8050b4bc ("block, partition: add partition_meta_info to hd_struct") Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Jens Axboe <axboe@fb.com>
