Revert "Audio: setParam improve status_t to Result consistency"

This commit broke sailfish build in V4 due to 
https://cs.corp.google.com/android/hardware/interfaces/audio/core/all-versions/default/include/core/all-versions/default/PrimaryDevice.impl.h?q=hardware/interfaces/audio/core/all-versions/default/include/core/all-versions/default/PrimaryDevice.impl.h:251

not being updated.

This is really strange as
 1) sailfish should not build the V4 code in the first place
 2) walleye is not broken although it should be the broken code
 3) neither treehugger nor my local builds found this issue

Revert to give the time to investigate.

This reverts commit 2c6755a0.
