test_sock_fields__detach() got called with a null pointer here when one
of the CHECKs or ASSERTs up to the test_sock_fields__open_and_load()
call resulted in a jump to the "done" label.
A skeletons *__detach() is not safe to call with a null pointer, though.
This led to a segfault.
Go the easy route and only call test_sock_fields__destroy() which is
null-pointer safe and includes detaching.
Came across this while looking[1] to introduce the usage of
bpf_tcp_helpers.h (included in progs/test_sock_fields.c) together with
vmlinux.h.
