[ Impact ]

selftest: netfilter: after upstream commit 2cf567f421dbfe7e53b7e5ddee9400da10efb75d
ipsec_offload test needs its source ip written into  the expected value, however the
complete patchset https://lore.kernel.org/lkml/20241010040027.21440-1-liuhangbin@gmail.com/
has a more comprehensive modification so this only fixes the test for the
current status (only patch 2/3 of the patchset applied).

Found on Oracular 6.11.0-17.17 and should be found on its derivatives /
backports.

Log output:

    # selftests: net: rtnetlink.sh
    # PASS: policy routing
    ---(snip)---
    # PASS: ipsec
    # FAIL: ipsec_offload incorrect driver data
    # FAIL: ipsec_offload
    # PASS: bridge fdb get

Verbose output should be like:

[ Test Plan ]

Compiled, boot tested and auto-tested on amd64.

[ Where Problems Could Occur ]

The fix affects only the failing ipsec_offload of the netfilter test.
