Oleg Drokin d89616fda8 Remove misguided HAVE_MUTEX_OWNER check 
It is just plain unsafe to peek inside in-kernel
mutex structure and make assumptions about what kernel
does with those internal fields like owner.

Kernel is all too happy to stop doing the expected things
like tracing lock owner once you load a tainted module
like spl/zfs that is not GPL.

As such you will get instant assertion failures like this:

  VERIFY3(((*(volatile typeof((&((&zo->zo_lock)->m_mutex))->owner) *)&
      ((&((&zo->zo_lock)->m_mutex))->owner))) == 
     ((void *)0)) failed (ffff88030be28500 == (null))
