fix another init regression 

This makes Beagle work again, instead of losing horribly because
the JTAG event handlers are no longer able to e.g. "runtest".  I
get the previous quirky behavior ... comes up OK but "reset halt"
somewhat mysteriously makes it all better.  (Instead of nothing
being able to work at all...)  However, I'm still seeing:

 The 'init' command must be used before 'init'.

That seems to come from invoking "jtag init", sometime after it
gets mapped to "ocd_jtag init", according to debug message traces.
