Bruce Evans fb717773e7 Fixed locking bugs in rev.1.346: 
(1) Don't attempt aquire the non-recursive lock sio_lock recursively.
    Doing so caused unbounded recursion in some setups.  E.g., if DDB,
    BREAK_TO_DEBUGGER and WITNESS are configured; if the debugger is
    entered using a break, then WITNESS will actually detect the invalid
    recursion and will add to it attempting to print a message about it.

(2) Don't use sio_lock before it has been initialized.  The old check
    (sio_inited != 0) didn't work when sio_inited was boolean because
    sio_inited was set too early, and became just wrong when sio_inited
    was changed to a tri-state variable in rev.1.348.
