selftests: rtnetlink.sh: remove esp4_offload after test

Browse Source 
[ Upstream commit 5b32321fdaf3fd1a92ec726af18765e225b0ee2b ]

The esp4_offload module, loaded during IPsec offload tests, should
be reset to its default settings after testing.
Otherwise, leaving it enabled could unintentionally affect subsequence
test cases by keeping offload active.

Without this fix:
$ lsmod | grep offload; ./rtnetlink.sh -t kci_test_ipsec_offload ; lsmod | grep offload;
PASS: ipsec_offload
esp4_offload           12288  0
esp4                   32768  1 esp4_offload

With this fix:
$ lsmod | grep offload; ./rtnetlink.sh -t kci_test_ipsec_offload ; lsmod | grep offload;
PASS: ipsec_offload
