Re: [PATCH 11/27] selftests/landlock: Assert helper results that are used afterwards

Some helpers check a result with EXPECT_*() and then use it:
cap_get_proc() in _init_caps() and _change_cap(), and
landlock_create_ruleset() in drop_access_rights(), create_domain() and
create_fs_domain().  On failure they pass NULL or -1 to the next calls,
which then fail with misleading messages.

Use ASSERT_*() for these checks, as create_scoped_domain() already does.
