wma: initialize prev_block_len_bits, next_block_len_bits, and block_len_bits.
The initial values are not checked against the number of block sizes. Initializing them to frame_len_bits will result in a block size index of 0 in these cases instead of something that might be out-of-range. Fixes Bug 81.
