firmware: Do not use WARN_ON(!spin_is_locked())

commit aee530cfecf4f3ec83b78406bac618cec35853f8 upstream.

spin_is_locked() always returns false for uniprocessor configurations
in several architectures, so do not use WARN_ON with it.
Use lockdep_assert_held() instead to also reduce overhead in
non-debug kernels.
