Disable the check in icu_setup() to see if a handler was already used as

Browse Source 
the current interrupt thread routines will guarantee the condition this is
checking for at a higher level but inthand_add() and inthand_remove() as
they currently exist don't satisfy this condition.  (Which does need to be
fixed but which will take a bit more work.)  This fixes shared interrupts.
