bluez5: fix ISO sequence numbering

Browse source 
Pass zero-length packets to the codec. BAP/ISO may use these to indicate
missing data.

Fix A2DP codecs to not parse input with spa_return_val_if_fail, that's
meant for assertions. Just return -EINVAL directly, it's normal that
input data may contain garbage.
