mknod: take sanity checks on mode into the very beginning
Note that applying umask can't affect their results. While that affects errno in cases like mknod("/no_such_directory/a", 030000) yielding -EINVAL (due to impossible mode_t) instead of -ENOENT (due to inexistent directory), IMO that makes a lot more sense, POSIX allows to return either and any software that relies on getting -ENOENT instead of -EINVAL in that case deserves everything it gets.
