    ktrace: change AST handler to require AST flag set
    
    When it was inline it made sense to depend on the existing nested check
    in KTRUSERRET() rather than adding a new td_flags flag.  However, since
    we now have a TDA_KTRACE flag anyway, we might as well check it and
    avoid the call.
