selftests/bpf: Fix error failure of case test_xdp_adjust_tail_grow
test_xdp_adjust_tail_grow failed with ipv6:
test_xdp_adjust_tail_grow:FAIL:ipv6 unexpected error: -28 (errno 28)
The reason is that this test case tests ipv4 before ipv6, and when ipv4
test finished, topts.data_size_out was set to 54, which is smaller than the
ipv6 output data size 114, so ipv6 test fails with NOSPC error.
Fix it by reset topts.data_size_out to sizeof(buf) before testing ipv6.
