block: fix an error code in add_partition()
[ Upstream commit 7bd897cfce1eb373892d35d7f73201b0f9b221c4 ]
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")
