Uwe Kleine-König 01b44ef2bf counter: Stop using dev_get_drvdata() to get the counter device
dev_get_drvdata() returns NULL since commit b56346ddbd ("counter: Use
container_of instead of drvdata to track counter_device") which wrongly
claimed there were no users of drvdata. Convert to container_of() to
fix a null pointer dereference.
