Although the "Segmentation fault" errors are fixed in the last commit,
run bpf_tcp_ca selftests (./test_progs -t bpf_tcp_ca) on a Loongarch
platform, still some other "ENOTSUPP" (-524) errors left since lacking
BPF trampoline on Loongarch:

Just like in ASSERT_OK(), this patch skips ENOTSUPP (524) and ENOTSUP (95)
in ASSERT_OK_PTR() too. With this change, the new output of bpf_tcp_ca
selftests look like:

'''
