af_lavcac3enc: fix assert failure "s->expect_len <= s->pending_data_size"

Browse Source 
The code handling input format negotiation incorrectly used the bps
value of the suggested input format instead of the format it was going
to actually use. As a result the player could abort with the above
assertion failure. Fix.
