ubi: block: fix memleak in ubiblock_create()
If idr_alloc() fails, dev->gd will be put after goto out_cleanup_disk in ubiblock_create(), but dev->gd has not been assigned yet at this time, and 'gd' will not be put anymore. Fix it by putting 'gd' directly. Signed-off-by: Li Nan <linan122@huawei.com> Reviewed-by: Zhihao Cheng <chengzhihao1@huawei.com> Signed-off-by: Richard Weinberger <richard@nod.at>
