test_cgcore_lesser_ns_open runs as root throughout and never changes its euid, so chowning the two cgroup.procs files to a non-root uid has no effect on the test. The ENOENT the test expects comes from the cgroup namespace delegation check in cgroup_procs_write_permission(): the source and destination cgroups must both be descendants of the namespace root captured at open time. That check does not depend on file ownership. In addition, the permission check only examines the common ancestor's cgroup.procs file (the test root here), which the chown calls do not touch. Remove the redundant chown calls and the now unused test_euid and cg_test_a_procs variables.
