avcodec/opus/enc_psy: init intensity_stereo for silent frames

Browse source 
Silent frames return early from ff_opus_psy_celt_frame_init before
intensity_stereo is set, but postencode_update reads it into
avg_is_band, causing a use-of-uninitialized-value. Set it to end_band
like the non-silent path does.
