debug: reduce some debugging noise

Resolve event_activation configure option just once.

Do not print debug_devs about 'bad' filtering, when
actually filter already printed reason for skipping

Do not trace more then once about backup being disabled.

No debug when unlinked file does not exists in pvscan.
