Subject: [PATCH bpf-next v4 6/6] selftest/bpf: Fix error usage of ASSERT_OK in xdp_adjust_tail.c

From: Xu Kuohai <xukuohai@...wei.com>

xdp_adjust_tail.c calls ASSERT_OK() to check the return value of
bpf_prog_test_load(), but the condition is not correct. Fix it.

Fixes: 791cad025051 ("bpf: selftests: Get rid of CHECK macro in xdp_adjust_tail.c")
