MFC sndstat.c 1.18

>   Convert sndstat_lock from a mutex to an sx lock.  sndstat_read()
>   holds sndstat_lock across a call to uiomove(), which is not legal
>   to do with a  mutex because of the possibility that the data transfer
>   could sleep because of a page fault.  It is not possible to just
>   unlock the mutex for the uiomove() call without introducing another
>   locking mechanism to prevent the body of sndstat_read() from being
>   re-entered.  Converting sndstat_lock to an sx lock is the least
>   complicated change.
