Audio PD daemon will allocate memory for audio PD dynamic loading
usage when it is attaching for the first time to audio PD. As
part of this, the memory ownership is moved to the VM where
audio PD can use it. In case daemon process is killed without any
impact to DSP audio PD, the daemon process will retry to attach to
audio PD and in this case memory won't be reallocated. If the invoke
fails due to any reason, as part of err_invoke, the memory ownership
is getting reassigned to HLOS even when the memory was not allocated.
At this time the audio PD might still be using the memory and an
attemp of ownership reassignment would result in memory issue.
