Subject: [PATCH 1/4] zdev: Enable running chzdev from unknown root devices

When a persistent device configuration is changed, chzdev tries to
find out if it needs to perform additional steps to make this change
persistent. If this check fails, for example because the root device
is located on a RAM-disk, or on a device type not managed by chzdev,
the tool reports an error and exits with non-zero exit code:

chzdev: Could not determine device that provides /

chzdev: Could not determine device that provides loop0

This behavior unnecessarily restricts chzdev from being used in
scripted environments like an installation initial RAM-disk.

Fix this by removing the non-zero exit code and moving the message to
verbose output mode only.
