virtual-device: Return empty no-match if unknown SCAN id is passed

Browse Source 
This matches the expectation. i.e. we return no-match and we do not
return a scanned print as we don't have anything for it. If we did
indeed return a scanned print, then fprintd would try to delete it
during enroll and would then fail.

Note that we do *not* return a DATA_NOT_FOUND error in the storage
device if the print does not exist. This is because not all devices
support reporting this error. It is therefore more sensible to handle it
gracefully and expect test setups to set the error explicitly for
testing purposes.
