    uart_dev_snps: Fix device probing
    
    The "uart_bus_probe" function is used as a generic part of uart probe
    logic. It returns a driver priority(negative number) if successful and
    an error code otherwise.
    Fix the error checking condition to account for that.
    Also, while here return "BUS_PROBE_VENDOR", instead of "0".
    This fixes uart on clearfog pro with recent DT.
