If xfrm_input() is called with UDP_ENCAP_ESPINUDP, the packet is
already processed in UDP layer that removes the UDP header.
Therefore, there should be no much difference to treat it as an
ESP packet in the XFRM stack.

Test: Enabled dir=in IPsec crypto offload, and verified IPv4
      UDP-encapsulated ESP packets on both wifi/cellular network
