registry: drop duplicate checks

In processMetrics drop duplicate checks. If the metricFamily exists we
already have a type check with the call to checkMetricConsistency. The
help string is already checked in the checkDescConsistency albeit only
if pedantic mode is enabled. However this is probably what is desired
anyway.
