Fix a bug in llvm-obdump(1) with the -macho flag disassembling an object

without symbols that makes calls through a symbol stub which were not
correctly being annotated with “## symbol stub for: _foo”.

Just adds the same parameters for getting the annotations from
DisAsm->getInstruction() and passing them to IP->printInst() from the
code above when boolean variable symbolTableWorked was true.
