ubi: Fix error for write access
When opening a device with write access, ubiblock_open returns an error code. Currently, this error code is -EPERM, but this is not the right value. The open function for other block devices returns -EROFS when opening read-only devices with FMODE_WRITE set. When used with dm-verity, the veritysetup userspace tool is expecting EROFS, and refuses to use the ubiblock device. Use -EROFS for ubiblock as well. As a result, veritysetup accepts the ubiblock device as valid.
