ubi: wl: Fix uninitialized variable
There is a potential execution path in which variable *err* is compared against UBI_IO_BITFLIPS without being properly initialized previously. Fix this by initializing variable *err* to 0. Addresses-Coverity-ID: 1477298 "(Uninitialized scalar variable") Fixes: 663586c0a892 ("ubi: Expose the bitrot interface") Signed-off-by: Gustavo A. R.
