As suggested by Jerome Marchand "The code in reset_store get the block device (bdget_disk()) but it does not put it (bdput()) when it's done using it. The usage count is therefor incremented but never decremented."
Hence, this patch introduces a call to bdput() to decrement the variable after usage.
