vdisp/aggregate codec probe: break if found

no need to iterate further if match found

If display misbehaves (outputs one codec multiple times), it causes
that codec to be elimited later (if the count != 1 for 2 devices) or
more in case of eg. 3 devices and the codec being listed 2-times for one
and no for another, it will be falsely accepted.
