Alexei Frolov da401abdfd pw_router: Remove logging
This removes all log statements from the static router. This is done as
there is no guarantee for what pw_log backend is used. In some systems,
logs may flow directly through the router, resulting in recursive calls
that cause a crash.

The user of the router can choose to check and log its return values if
the operation is safe.
