Use landlock_cred(file->f_cred)->domain instead of landlock_get_current_domain() in security_file_open() hook implementation. This should not change the current behavior but could avoid potential race conditions in case of current task's credentials change. This will also ensure consistency with upcoming audit support relying on file->f_cred. Add and use a new get_fs_domain() helper to mask non-filesystem domains. file->f_cred is set by path_openat()/alloc_empty_file()/init_file() just before calling security_file_alloc().
