qlcnic: fix estimation of receive MSS in case of LRO for 83xx adapter

Browse source

Set gso_size to MSS obtained from adapter to avoid incorrect estimation
of receive MSS, which would lead to delayed ACKs in some traffic patterns

Example:
Send two or three packets and wait for ack and only then send
remaining packets.
