ASoC: SOF: ipc3-control: Merge functions to handle bytes_ext get variants

Browse Source 
The code for bytes_ext_get and bytes_ext_volatile_get is identical with
the only difference is that in case of volatile_get we refresh the data
from the DSP before returning it to user space.

Convert the callbacks to a simple wrapper for the same function.
