[PATCH v1] mtd: nandbiterrs: Have init function return 0 on success

[Marc Gonzalez]

The init function currently returns -EIO on success. This behavior
was probably chosen in order to avoid a subsequent rmmod, but this
complicates failure detection from user-space.

I'm not sure failures are reported as expected. I would expect
the test to report a failure if the driver cannot fix less than
$STRENGTH bit flips, but it doesn't, AFAICT.
cf. incremental_errors_test which sets err to 0 in the 
"After %d biterrors per subpage, read reported error %d\n"
code path.
