USB: lower "Device is not authorized for usage" message to info
This message is not a useful error in practice:
- when using tools such as usbguard, the message is always printed but
it does not presume anything regarding the actual device acceptance
(later 'authorized to connect' message is at info level, and not
displayed on console)
- this can be a source of flood if a usb device connection is flaky
- ... and it is only displayed as the result of an admin action
(modifying authorized_default), working as intended, so not likely
to be an error.
This is still useful to know when looking at usb devices problems, so
info seems appropriate for this class of messages together with the
later eventual authorized message.
