ASoC: Intel: Skylake: Fix parameter overwrite for KPB Module

KPB module default parameter were overwritten by the dynamic instance
id once use case is executed. This will cause module crash from
subsequent execution of use case as the updated parameters are used.

So instead of over writing the default parameter, make a copy and
update the module parameter and use this in IPC message.
