Pass missing parameter to real function

Pass missing parameter to real function

- Issue:
After reprepare_on_demand(), the client handle is missing.

- Solution:
Previous code does not pass all neccessary parameters, so the function
can write value into arbitrary pointer. And this pointer access can
cause critical memory crash. Thus, this patch fixes the code to make
sure the tts_ipc module pass all proper parameters to actual function in
tts_dbus and tts_tidl module.
