avf: Handle chain buffer in TX properly
For chain buffer, need to traverse b->next_buffer to transmit all buffers in the chain. Only set EOP at the last descriptor in the chain to signal this is a chain descriptor. Introduce slow path to handle ring wrap. This is needed because chain buffer may consist of multiple pieces and it may span from near the end of the ring to the beginning of the ring.
