Currently usrcnt is {in,de}cremented in .hw_{params,free} callbacks, but .hw_free may be called multiple times without calling .hw_params. this causes the usrcnt be decremented wrongly. This patch allows .hw_{params,free} to be called only in pairs for the same stream which balances the {in,de}crement of usrcnt.
