    target: fix segmentation fault on target create
    
    In the unusual (and even incorrect) case of running the command
    target create ...
    before defining an adapter and the associated transport, the
    command causes a segmentation fault. E.g.:
            openocd -c 'target create cpu cortex-m -endian little'
    
    Check that get_current_transport() returns a valid pointer before
    referencing it.
