Routine Description:

    This is the initialization routine for the SMB device driver.
    This routine creates the device object for the SMB
    device and calls a routine to perform other driver initialization.

Arguments:

    DriverObject - Pointer to driver object created by the system.

Return Value:

    NTSTATUS - The function value is the final status from the initialization
        operation.
