Simplify map_or_log_err

All (non-test) invocations use the same second argument `Ok` (which
actually acts as a 1-arg closure `|v| Ok(v)`), so no need to have it as
a parameter.  The common second argument just maps `Ok(v)` to `Ok(v)`,
which means that `map_err()` can be used instead of `map_or_else()`,
and the same type parameter is used for both input and output.

Test: legacykeystore_test
Test: keystore2_test
Flag: None, pure refactor
