i40e: reinit buffer size each time

Browse source 
When cleaning the ARQ, we must reinitialize the buffer size each time we
go through the loop, because i40e_clean_arq_element returns the message
length in the same field. Without this change, subsequent messages can
be truncated to the length of the previous message.
