  Because of this, moved some declarations to start of the block

2a238075dc Decoder: In case of no free buffers, release all buffers 
When decoding erroneous streams, decoder may run out of all buffers
used to hold reference pictures and MV data. In such cases, ignore
all frames till the next IDR frame and then release all buffers while
decoding the IDR frame.
