ubi: Fix rollback for explicit UBI device numbers
ubi_init_attach() rolls back module initialization failures by scanning
ubi_devices[0..i-1], where i is the mtd= parameter index. That assumes
the parameter index matches the UBI device number.
That assumption is not true when mtd= specifies an explicit ubi_num. A
successfully attached device can be stored at a higher ubi_devices[]
slot, and a later failure can miss it during rollback.
Scan the full ubi_devices[] array and detach by the actual array index,
matching the way UBI devices are stored.
Fixes: 83ff59a06663 ("UBI: support ubi_num on mtd.ubi command line")
