c9614b8df9 Fix for write null dereferencing in AAC frame decode 
Audio Object type(AOT) should be same across init and
execute calls. This check was missing when AOT is
not SBR and PS and hence added as fix for this bug.
For AOTs, SBR and PS since this value is re-read at
a later point, check already present would be fine.
