Fix: sessiond: silent kernel notifier registration error

When a kernel notifier fails to be registered, the error is silently
ignored because of a missing jump to the error label.

This was noticed while debugging an unrelated problem where the kernel
tracer would fail to add a userspace probe to a semaphore-protected SDT
probe.
