avcodec/roqaudioenc: Avoid redundant free of unallocated buffer

Browse Source 
If allocating a buffer in RoQ DPCM encoder's init function failed,
the close function would be called manually; all this function does is
freeing said buffer, but given that it has not been allocated at all,
this is unnecessary.
