udevd: always try to find an idle worker instead of forking a new one

Browse Source 
We special-handle events with a TIMEOUT= set, so they don't get queued
or wait for parent events to finish, to make sure we can handle them
as fast as possible.

With this change we first try to find an idle worker process before
forking a new one.
