idpf: fix handling rsc packet with a single segment

Browse source 
Handle rsc packet with a single segment same as a multi
segment rsc packet so that CHECKSUM_PARTIAL is set in the
skb->ip_summed field. The current code is passing CHECKSUM_NONE
resulting in TCP GRO layer doing checksum in SW and hiding the
issue. This will fail when using dmabufs as payload buffers as
skb frag would be unreadable.
