Subject: mtd: mtdpart: fix add_mtd_partitions error path

From: Boris BREZILLON <[email protected]>

commit e5bae86797141e4a95e42d825f737cb36d7b8c37 upstream.

If we fail to allocate a partition structure in the middle of the partition creation process, the already allocated partitions are never removed, which means they are still present in the partition list and their resources are never freed.
