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")
