net/ice: fix outer UDP checksum offload

[ upstream commit 10fbf1af4c5548b85b4791d241cdef62755240b1 ]

Currently, when dealing with UDP tunnel pkts checksum offloading,
the outer-udp checksum will be offloaded by default. So the
'csum set outer-udp hw/sw' command does not work.

This patch fixes judgment of the EIPT flag and enables the
'csum set outer-udp hw/sw' command by adding judgment for the
outer-udp checksum offload flag.

Fixes: bd70c45 ("net/ice: support Tx checksum offload for tunnel")
