kmemtrace: Fix up tracer registration
Commit ddc1637af217dbd8bc51f30e6d24e84476a869a6 ("kmemtrace: Print
binary output only if 'bin' option is set") ended up inverting the
error detection logic. register_tracer() returns 0 on success,
which this change caused to treat as an error, resulting in:
[ 0.132000] Warning: could not register the kmem tracer
as well as bailing out of the initcall with an error value. This
restores the old logic.
