err is initialized to -EINVAL when it is declared. It is not reset until

Removing that line obviates the need for the martian_source_keep_err
label
so delete it.

The comments above and the code below don't sync up. The function
fib_validate_source can return either -EINVAL, -EXDEV, 0, or 1. The
fact is this may be acceptable as long as all callers of
ip_route_input_slow will handle a non-zero value as an error and it
doesn't care about what the actual return value is. If that is what you
are going for here at least the comment should be updated, and we should
be explicit somewhere about documenting the return values.
Actually this patch is correct. I got my wires a bit crossed and
misread martian_source vs martian_source_keep_err.
