bpf: Fixed session affinity test after naming conflict
bpf: Fixed session affinity test after naming conflict

PR #20615 added a new test which relied on the name of the XDP entry
program. PR #19735 changed this name. They were merged within short time
of each other, since the changes were not overlapping no merge conflict
resulted.

This commit fixes the test so it works with the new name.
